(venv) blau@MacBookPro glue2 % python -m py_compile modules.py Could not import runpy module Traceback (most recent call last): File "/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/runpy.py", line 15, in <module> import importlib.util File "/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/importlib/util.py", line 2, in <module> from . import abc File "/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/importlib/abc.py", line 17, in <module> from typing import Protocol, runtime_checkable File "/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/typing.py", line 23, in <module> import contextlib File "/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/contextlib.py", line 6, in <module> from functools import wraps File "/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/functools.py", line 22, in <module> from types import GenericAlias ImportError: cannot import name 'GenericAlias' from 'types' (/Users/blau/access/ipf/ipf/ipf/glue2/types.py)
