Summary

Utils installaion tries to install as user, can't due to no user home folder

What happened?

I'm hosting the Modmail bot in Docker. There is no home folder for the user running the bot, so the installation fails trying to user-install the dependency.

Error Logs

discord.ext.commands.errors.ExtensionFailed: Extension 'plugins.Jerrie-Aries.modmail-plugins.utils-master.utils' raised an error: RuntimeError: Unable to install requirements:
ERROR: Could not install packages due to an OSError: [Errno 13] Permission denied: '/home/modmail'
Check the permissions.


The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/modmailbot/cogs/plugins.py", line 404, in plugins_add
    await self.load_plugin(plugin)
  File "/modmailbot/cogs/plugins.py", line 265, in load_plugin
    raise InvalidPluginError("Cannot load extension, plugin invalid.") from exc
cogs.plugins.InvalidPluginError: Cannot load extension, plugin invalid.

No response

Additional Information

Fix idea: ability to override the venv detection with a ENV var, to use a global install in docker.

[laundmo]

there is a USING_DOCKER env set by the Dockerfile of Modmail which can be used

nevermind, this is a Modmail side issue: modmail-dev/Modmail#3323
