title: ModuleNotFoundError: No module named 'discord_webhook'
body: <p>So I have a docker container which is trying to use a python module called discord_webhook, to integrate my web service to discord, however when I start the container, it instantly errors out saying</p>
  <pre><code>houdini_blizzard_1  |   File &quot;/usr/src/houdini/houdini/plugins/discordwebhook/__init__.py&quot;, line 3, in &lt;module&gt;
  houdini_blizzard_1  |     from discord_webhook import DiscordWebhook, DiscordEmbed
  houdini_blizzard_1  | ModuleNotFoundError: No module named 'discord_webhook'
  </code></pre>
  <p>I used docker exec -it {container-id} sh to connect to the container, and ran pip install discord_webhook. It installed fine with no errors. But I then I added discord_webhook module back to the <code>__init__.py</code> of the plugin, then restarted the docker container, but it still gave the same error. When I <code>ls</code> in <code>/usr/local/lib/python3.9/site-packages/discord_webhook</code> there are these files/folders</p>
  <pre><code>__init__.py  __main__.py  __pycache__  webhook.py
  </code></pre>
  <p>That should mean that discord_webhook is installed properly. So why is python saying the module isn't found?</p>
