<h2>Confusion of location (GIT installation)<a class="headerlink" href="#confusion-of-location-git-installation" title="Permalink to this headline"></a></h2>
<p>When doing the <a class="reference internal" href="Installation-Git.html"><span class="doc std std-doc">Git installation</span></a>, some may be confused and install Evennia in the wrong location. After following the instructions (and using a virtualenv), the folder structure should look like this:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">muddev</span><span class="o">/</span>
<span class="n">evenv</span><span class="o">/</span>
<span class="n">evennia</span><span class="o">/</span>
<span class="n">mygame</span><span class="o">/</span>
</pre></div>
</div>
<p>The evennia code itself is found inside <code class="docutils literal notranslate"><span class="pre">evennia/evennia/</span></code> (so two levels down). Your settings file
is <code class="docutils literal notranslate"><span class="pre">mygame/server/conf/settings.py</span></code> and the <em>parent</em> setting file is <code class="docutils literal notranslate"><span class="pre">evennia/evennia/settings_default.py</span></code>.</p>
</section>
<section id="virtualenv-setup-fails">
<h2>Virtualenv setup fails<a class="headerlink" href="#virtualenv-setup-fails" title="Permalink to this headline"></a></h2>
<p>When doing the <code class="docutils literal notranslate"><span class="pre">python3.11</span> <span class="pre">-m</span> <span class="pre">venv</span> <span class="pre">evenv</span></code> step, some users report getting an error; something like:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>Error: Command &#39;[&#39;evenv&#39;, &#39;-Im&#39;, &#39;ensurepip&#39;, &#39;--upgrade&#39;, &#39;--default-pip&#39;]&#39;
returned non-zero exit status 1
</pre></div>
</div>
<p>You can solve this by installing the <code class="docutils literal notranslate"><span class="pre">python3.11-venv</span></code> package or equivalent for your OS. Alternatively you can bootstrap it in this way:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>python3.11 -m --without-pip evenv
</pre></div>
</div>
<p>This should set up the virtualenv without <code class="docutils literal notranslate"><span class="pre">pip</span></code>. Activate the new virtualenv and then install pip from within it:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>python -m ensurepip --upgrade
</pre></div>
</div>
<p>If that fails, a worse alternative to try is</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>curl https://bootstrap.pypa.io/get-pip.py | python3.10 (linux/unix/WSL only)
</pre></div>
</div>
<p>Either way, you should now be able to continue with the installation.</p>

<h2>Linux Troubleshooting<a class="headerlink" href="#linux-troubleshooting" title="Permalink to this headline"></a></h2>
<ul class="simple">
<li><p>If you get an error when installing Evennia (especially with lines mentioning
failing to include <code class="docutils literal notranslate"><span class="pre">Python.h</span></code>) then try <code class="docutils literal notranslate"><span class="pre">sudo</span> <span class="pre">apt-get</span> <span class="pre">install</span> <span class="pre">python3-setuptools</span> <span class="pre">python3-dev</span></code>. Once installed, run <code class="docutils literal notranslate"><span class="pre">pip</span> <span class="pre">install</span> <span class="pre">-e</span> <span class="pre">evennia</span></code> again.</p></li>
<li><p>When doing a <a class="reference internal" href="Installation-Git.html"><span class="doc std std-doc">git install</span></a>, some not-updated Linux distributions may give errors
about a too-old <code class="docutils literal notranslate"><span class="pre">setuptools</span></code> or missing <code class="docutils literal notranslate"><span class="pre">functools</span></code>. If so, update your environment
with <code class="docutils literal notranslate"><span class="pre">pip</span> <span class="pre">install</span> <span class="pre">--upgrade</span> <span class="pre">pip</span> <span class="pre">wheel</span> <span class="pre">setuptools</span></code>. Then try <code class="docutils literal notranslate"><span class="pre">pip</span> <span class="pre">install</span> <span class="pre">-e</span> <span class="pre">evennia</span></code> again.</p></li>
<li><p>One user reported a rare issue on Ubuntu 16 is an install error on installing Twisted; <code class="docutils literal notranslate"><span class="pre">Command</span> <span class="pre">&quot;python</span> <span class="pre">setup.py</span> <span class="pre">egg_info&quot;</span> <span class="pre">failed</span> <span class="pre">with</span> <span class="pre">error</span> <span class="pre">code</span> <span class="pre">1</span> <span class="pre">in</span> <span class="pre">/tmp/pip-build-vnIFTg/twisted/</span></code> with errors like <code class="docutils literal notranslate"><span class="pre">distutils.errors.DistutilsError:</span> <span class="pre">Could</span> <span class="pre">not</span> <span class="pre">find</span> <span class="pre">suitable</span> <span class="pre">distribution</span> <span class="pre">for</span> <span class="pre">Requirement.parse('incremental&gt;=16.10.1')</span></code>.

<li><p>Users of Fedora (notably Fedora 24) has reported a <code class="docutils literal notranslate"><span class="pre">gcc</span></code> error saying the directory
<code class="docutils literal notranslate"><span class="pre">/usr/lib/rpm/redhat/redhat-hardened-cc1</span></code> is missing, despite <code class="docutils literal notranslate"><span class="pre">gcc</span></code> itself being installed. <a class="reference external" href="https://gist.github.com/yograterol/99c8e123afecc828cb8c">The
confirmed work-around</a> seems to be to install the <code class="docutils literal notranslate"><span class="pre">redhat-rpm-config</span></code> package with e.g. <code class="docutils literal notranslate"><span class="pre">sudo</span> <span class="pre">dnf</span> <span class="pre">install</span> <span class="pre">redhat-rpm-config</span></code>.</p></li>
<li><p>Some users trying to set up a virtualenv on an NTFS filesystem find that it fails due to issues
with symlinks not being supported. Answer is to not use NTFS (seriously, why would you do that to yourself?)</p></li>

<section id="mac-troubleshooting">
<h2>Mac Troubleshooting<a class="headerlink" href="#mac-troubleshooting" title="Permalink to this headline"></a></h2>
<ul class="simple">
<li><p>Some Mac users have reported not being able to connect to <code class="docutils literal notranslate"><span class="pre">localhost</span></code> (i.e. your own computer). If so, try to connect to <code class="docutils literal notranslate"><span class="pre">127.0.0.1</span></code> instead, which is the same thing. Use port 4000 from mud clients and port 4001 from the web browser as usual.</p></li>
<li><p>If you get a <code class="docutils literal notranslate"><span class="pre">MemoryError</span></code> when starting Evennia, or when looking at the log, this may be due to an sqlite versioning issue. <a class="reference external" href="https://github.com/evennia/evennia/discussions/2637">A user in our forums</a> found a working solution for this. <a class="reference external" href="https://github.com/evennia/evennia/issues/2854">Here</a> is another variation to solve it.</p></li>
</ul>
</section>
<section id="windows-troubleshooting">
<h2>Windows Troubleshooting<a class="headerlink" href="#windows-troubleshooting" title="Permalink to this headline"></a></h2>
<ul class="simple">
<li><p>If you install with <code class="docutils literal notranslate"><span class="pre">pip</span> <span class="pre">install</span> <span class="pre">evennia</span></code> and find that the <code class="docutils literal notranslate"><span class="pre">evennia</span></code> command is not available, run <code class="docutils literal notranslate"><span class="pre">py</span> <span class="pre">-m</span> <span class="pre">evennia</span></code> once. This should add the evennia binary to your environment. If this fails, make sure you are using a <a class="reference internal" href="Installation-Git.html#virtualenv"><span class="std std-doc">virtualenv</span></a>. Worst case, you can keep using <code class="docutils literal notranslate"><span class="pre">py</span> <span class="pre">-m</span> <span class="pre">evennia</span></code> in the places where the <code class="docutils literal notranslate"><span class="pre">evennia</span></code> command is used.</p></li>
<li><p>Install Python <a class="reference external" href="https://www.python.org/downloads/windows/">from the Python homepage</a>. You will need to be a Windows Administrator to install packages.</p></li>
<li><p>When installing Python, make sure to check-mark <em>all</em> install options, especially the one about making Python available on the path (you may have to scroll to see it). This allows you to
just write <code class="docutils literal notranslate"><span class="pre">python</span></code> in any console without first finding where the <code class="docutils literal notranslate"><span class="pre">python</span></code> program actually sits on your hard drive.</p></li>
<li><p>If you get a <code class="docutils literal notranslate"><span class="pre">command</span> <span class="pre">not</span> <span class="pre">found</span></code> when trying to run the <code class="docutils literal notranslate"><span class="pre">evennia</span></code> program after installation, try closing the Console and starting it again (remember to re-activate the virtualenv if you use one!). Sometimes Windows is not updating its environment properly and <code class="docutils literal notranslate"><span class="pre">evennia</span></code> will be available only in the new console.</p></li>
<li><p>If you installed Python but the <code class="docutils literal notranslate"><span class="pre">python</span></code> command is not available (even in a new console), then
you might have missed installing Python on the path. In the Windows Python installer you get a list of options for what to install. Most or all options are pre-checked except this one, and you may even have to scroll down to see it. Reinstall Python and make sure it’s checked.</p></li>
<li><p>If your MUD client cannot connect to <code class="docutils literal notranslate"><span class="pre">localhost:4000</span></code>, try the equivalent <code class="docutils literal notranslate"><span class="pre">127.0.0.1:4000</span></code>
instead. Some MUD clients on Windows does not appear to understand the alias <code class="docutils literal notranslate"><span class="pre">localhost</span></code>.</p></li>
<li><p>Some Windows users get an error installing the Twisted ‘wheel’. A wheel is a pre-compiled binary
package for Python. A common reason for this error is that you are using a 32-bit version of Python, but Twisted has not yet uploaded the latest 32-bit wheel. Easiest way to fix this is to install a slightly older Twisted version. So if, say, version <code class="docutils literal notranslate"><span class="pre">22.1</span></code> failed, install <code class="docutils literal notranslate"><span class="pre">22.0</span></code> manually with <code class="docutils literal notranslate"><span class="pre">pip</span> <span class="pre">install</span> <span class="pre">twisted==22.0</span></code>. Alternatively you could check that you are using the 64-bit version of Python and uninstall any 32bit one. If so, you must then <code class="docutils literal notranslate"><span class="pre">deactivate</span></code> the virtualenv, delete the <code class="docutils literal notranslate"><span class="pre">evenv</span></code> folder and recreate it anew with your new Python.</p></li>
<li><p>If you’ve done a git installation, and your server won’t start with an error message like <code class="docutils literal notranslate"><span class="pre">AttributeError:</span> <span class="pre">module</span> <span class="pre">'evennia'</span> <span class="pre">has</span> <span class="pre">no</span> <span class="pre">attribute</span> <span class="pre">'_init'</span></code>, it may be a python path issue. In a terminal, cd to <code class="docutils literal notranslate"><span class="pre">(your</span> <span class="pre">python</span> <span class="pre">directory)\site-packages</span></code> and run the command <code class="docutils literal notranslate"><span class="pre">echo</span> <span class="pre">&quot;C:\absolute\path\to\evennia&quot;</span> <span class="pre">&gt;</span> <span class="pre">local-vendors.pth</span></code>. Open the created file in your favorite IDE and make sure it is saved with <em>UTF-8</em> encoding and not <em>UTF-8 with BOM</em>.</p></li>
<li><p>If your server won’t start, with no error messages (and no log files at all when starting from
scratch), try to start with <code class="docutils literal notranslate"><span class="pre">evennia</span> <span class="pre">ipstart</span></code> instead. If you then see an error about <code class="docutils literal notranslate"><span class="pre">system</span> <span class="pre">cannot</span> <span class="pre">find</span> <span class="pre">the</span> <span class="pre">path</span> <span class="pre">specified</span></code>, it may be that the file <code class="docutils literal notranslate"><span class="pre">evennia\evennia\server\twistd.bat</span></code> has the wrong path to the <code class="docutils literal notranslate"><span class="pre">twistd</span></code> executable. This file is auto-generated, so try to delete it and then run <code class="docutils literal notranslate"><span class="pre">evennia</span> <span class="pre">start</span></code> to rebuild it and see if it works. If it still doesn’t work you need to open it in a text editor like Notepad. It’s just one line containing the path to the <code class="docutils literal notranslate"><span class="pre">twistd.exe</span></code> executable as determined by Evennia. If you installed Twisted in a non-standard location this might be wrong and you should update the line to the real location.</p></li>
<li><p>Some users have reported issues with Windows WSL and anti-virus software during Evennia
development. Timeout errors and the inability to run <code class="docutils literal notranslate"><span class="pre">evennia</span> <span class="pre">connections</span></code> may be due to your anti-virus software interfering. Try disabling or changing your anti-virus software settings.</p></li>
