The changes in this commit
https://github.com/django/django/commit/ec6d2531c59466924b645f314ac33f54470d7ac3
to def get_child_arguments() of django/utils/autoreload.py cause a crash
when running manage.py as a script from a conda env. For example:
{{{miniconda3/envs/promotion_tool_38/bin/manage.py runserver
10.12.123.45:8183}}} no longer works and gives this stacktrace:
{{{

if __main__.__spec__ is not None and __main__.__spec__.parent:
AttributeError: module '__main__' has no attribute '__spec__'
}}}
The work around for this is to explicitly call the actual manage.py inside
the EGG-INFO like this:
{{{
~/miniconda3/envs/promotion_tool_38/lib/python3.8/site-
packages/promotion_tool-1.0.28-py3.7.egg/EGG-INFO/scripts/manage.py
runserver 10.12.123.45:8183
}}}
After reverting the changes locally found in this method
"get_child_arguments" in django/utils/autoreload.py in the commit above,
the command {{{miniconda3/envs/promotion_tool_38/bin/manage.py runserver
10.12.123.45:8183}}} works again, or if inside the conda env then just
{{{manage.py runserver 10.12.123.45:8183}}} works.
