macOS ModuleNotFoundError: No module named 'WDL'

[slw287r]

Hi developers,

On macOS with case-sensitive enabled, miniwdl will fail to find the wdl package:

% miniwdl
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.9/bin/miniwdl", line 5, in <module>
    from WDL.CLI import main
ModuleNotFoundError: No module named 'WDL'

The issue is caused by miniwdl's from WDL.CLI import main command using uppercase WDL.

The wdl package folder is in lowercase:

/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/wdl

Change the import command to from wdl.CLI import main fixed the issue.

PS: More exceptions after running test. Maybe better renaming wdl folder to WDL.

Cheers, Richard

Thanks -- I suspect a temporary workaround is to use the Homebrew or miniconda3 versions of Python3 instead of the macOS built-in version. The latter has several odd things about it, perhaps (I need to look into it) one of which may explain how you got the lower-case wdl folder in the first place. I will keep this open as I think it is probably a real roadbump.
