Pydevd-odoo does not work for Python 3.8

[joao-p-marques]

When I try to run pydevd-odoo in Python 3.8 along with debugpy, it introduces an error that prevents it from running

The error is the following:

root@631a7db35ba5:/# python -m debugpy -h
Traceback (most recent call last):
  File "/usr/local/lib/python3.8/runpy.py", line 194, in _run_module_as_main

    exec(code, run_globals)

    elif not mod.__file__.startswith(root):
AttributeError: 'NoneType' object has no attribute 'startswith'

I associate this bug with pydev-odoo because:

@joao-p-marques Please see fabioz/debugpy@792458b .

Seems it is not an issue with this module, but ratther pydevd.

Thanks @gdgellatly. I will test if that fixes the issue.

My only question is why did installing pydevd-odoo trigger the issue? pydevd should already come from debugpy right? Does this have to do with some specific pydevd version that pydevd-odoo installs?

@joao-p-marques No it is nothing like that. It is simply that you happened to install a pydevd extension. If it wasn't this module it would have been another. The error is in the extension loading mechanism of pydevd. Looking at the failing code it is quite obviously a pydevd issue and not to do with this module.

@joao-p-marques I have checked and this issue was closed upstream by this commit microsoft/debugpy@ac05dab
