<h2>Confusion of location (GIT installation)<aclass="headerlink"href="#confusion-of-location-git-installation"title="Permalink to this headline">¶</a></h2>
<p>It’s common to be confused and install Evennia in the wrong location. After following the
<aclass="reference internal"href="Installation-Git.html"><spanclass="doc std std-doc">git install</span></a> instructions, the folder structure should look like this:</p>
<p>The evennia code itself is found inside <codeclass="docutils literal notranslate"><spanclass="pre">evennia/evennia/</span></code> (so two levels down). Your settings file
is <codeclass="docutils literal notranslate"><spanclass="pre">mygame/server/conf/settings.py</span></code> and the <em>parent</em> setting file is <codeclass="docutils literal notranslate"><spanclass="pre">evennia/evennia/settings_default.py</span></code>.</p>

<p>You can solve this by installing the <codeclass="docutils literal notranslate"><spanclass="pre">python3.10-venv</span></code> package or equivalent for your OS. Alternatively

<li><p>If you get an error when installing Evennia (especially with lines mentioning

about a too-old <codeclass="docutils literal notranslate"><spanclass="pre">setuptools</span></code> or missing <codeclass="docutils literal notranslate"><spanclass="pre">functools</span></code>. If so, update your environment

<h2>Windows Troubleshooting<aclass="headerlink"href="#windows-troubleshooting"title="Permalink to this headline">¶</a></h2>
<ulclass="simple">
<li><p>Install Python <aclass="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 <codeclass="docutils literal notranslate"><spanclass="pre">python</span></code> in any console without first finding where the <codeclass="docutils literal notranslate"><spanclass="pre">python</span></code>
program actually sits on your hard drive.</p></li>
<li><p>If you get a <codeclass="docutils literal notranslate"><spanclass="pre">command</span><spanclass="pre">not</span><spanclass="pre">found</span></code> when trying to run the <codeclass="docutils literal notranslate"><spanclass="pre">evennia</span></code> program after installation, try closing the
Console and starting it again (remember to re-activate the virtualenv!). Sometimes Windows is not updating
its environment properly.</p></li>
<li><p>If you installed Python but the <codeclass="docutils literal notranslate"><spanclass="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 <codeclass="docutils literal notranslate"><spanclass="pre">localhost:4000</span></code>, try the equivalent <codeclass="docutils literal notranslate"><spanclass="pre">127.0.0.1:4000</span></code>
instead. Some MUD clients on Windows does not appear to understand the alias <codeclass="docutils literal notranslate"><spanclass="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 <codeclass="docutils literal notranslate"><spanclass="pre">22.1</span></code> failed, install <codeclass="docutils literal notranslate"><spanclass="pre">22.0</span></code> manually with <codeclass="docutils literal notranslate"><spanclass="pre">pip</span><spanclass="pre">install</span><spanclass="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 <codeclass="docutils literal notranslate"><spanclass="pre">deactivate</span></code> the virtualenv, delete the <codeclass="docutils literal notranslate"><spanclass="pre">evenv</span></code> folder
and recreate it anew with your new Python.</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 <codeclass="docutils literal notranslate"><spanclass="pre">evennia</span><spanclass="pre">ipstart</span></code> instead. If you then see an error about <codeclass="docutils literal notranslate"><spanclass="pre">system</span><spanclass="pre">cannot</span><spanclass="pre">find</span><spanclass="pre">the</span><spanclass="pre">path</span><spanclass="pre">specified</span></code>, it may be that the file <codeclass="docutils literal notranslate"><spanclass="pre">evennia\evennia\server\twistd.bat</span></code> has the wrong
path to the <codeclass="docutils literal notranslate"><spanclass="pre">twistd</span></code> executable. This file is auto-generated, so try to delete it and then run
<codeclass="docutils literal notranslate"><spanclass="pre">evennia</span><spanclass="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 <codeclass="docutils literal notranslate"><spanclass="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 <codeclass="docutils literal notranslate"><spanclass="pre">evennia</span><spanclass="pre">connections</span></code> may be due to your anti-
virus software interfering. Try disabling or changing your anti-virus software settings.</p></li>
