ImportError: Could not find ''

Config file:

[Application]
name=TF2 Discord
version=3.1.0
entry_point=..\src\main:tf2_discord
console=false
license_file=..\LICENSE

[Python]
version=3.6.5
format=bundled

[Include]
packages = pypresence
    valve
    psutil

files = ..\LICENSE
    ..\README.md

Relevant file-structure: image

I guessed that this was related to the packages and/or file includes due to the nature of the error. Or that it was an issue with whitespace? But removing the [Include] section entirely leaves me with an identical error, so I have absolutely no idea.

takluyver commented 3 years ago

I think this line is the problem:

entry_point=..\src\main:tf2_discord

The first part of that expects an importable module name, not a path. Something like mymod:main, where you can do from mymod import main.

The error message could be clearer, though.

mirrorcult commented 3 years ago

Ahh, that makes sense. Yeah, the error message could be a little more helpful.
