ValueError on Conda in windows environment

[Jokipii]

I got ValueError, when I tried to import typed_astunpare in Conda environment:

Python 3.7.3 | packaged by conda-forge | (default, Jul  1 2019, 22:01:29) [MSC v.1900 64 bit (AMD64)] :: Anaconda, Inc. on win64

  File "C:\ProgramData\Anaconda3\envs\greencarbon\lib\site-packages\version_query-1.0.5-py3.7.egg\version_query\py_query.py", line 42, in query_package_folder

ValueError: ([WindowsPath('C:/ProgramData/Anaconda3/envs/greencarbon/lib/site-packages/typed_astunparse-2.1.4-py3.7.egg/typed_astunparse'), WindowsPath('C:/ProgramData/Anaconda3/envs/greencarbon/lib/site-packages/typed_astunparse-2.1.4-py3.7.egg'), WindowsPath('C:/ProgramData/Anaconda3/envs/greencarbon/lib/site-packages'), WindowsPath('C:/ProgramData/Anaconda3/envs/greencarbon/lib'), WindowsPath('C:/ProgramData/Anaconda3/envs/greencarbon'), WindowsPath('C:/ProgramData/Anaconda3/envs'), WindowsPath('C:/ProgramData/Anaconda3'), WindowsPath('C:/ProgramData'), WindowsPath('C:/')], [], [])

In my case 'PNG-INFO' is located on 'C:\ProgramData\Anaconda3\envs\greencarbon\lib\site-packages\typed_astunparse-2.1.4-py3.7.egg\EGG-INFO' directory.
Method 'query_package_folder' in 'py_query.py' tries to find it in 'EGG-INFO' directory, but only if directory name is in lowercase 'egg-info'.

@Jokipii Sorry, could you try the fix I just implemented and tell me if it fixes the problem? I don't have any Anaconda on Windows install so I can't test it myself...

Please install this:

pip3 install git+https://github.com/mbdevpl/version-query.git@feature/anaconda-windows

... and then re-run whatever you were trying to do in typed-astunparse#6 to check if it breaks again.

The installation method above means installing directly from my repo, from a specific git branch feature/anaconda-windows on which I added the fix. Other uses are described here: https://stackoverflow.com/questions/20101834/pip-install-from-git-repo-branch
