ModuleNotFoundError: No module named 'gevent.__hub_local'

Hi! when building a distributable binary, and try to execute it the following error appear:

Traceback (most recent call last):

@sedir I do not know why it appeared … but I fixed it by installing these packages with this version: gevent==1.2.2 Eel==0.9.7 gevent-websocket==0.10.1 greenlet==0.4.13 PyInstaller==3.3.1

The reason for using the -m eel syntax is that it automatically includes some necessary modules that pyinstaller leaves out.

If you look at the code you can see the actual pyinstaller command that it calls

I don’t think pyinstaller is clever enough to know that Eel uses gevent and bottle, which is why you need the --hidden-import part
