New submission from Ronald Oussoren <[email protected]>:
Using Python 3.7.2 on macOS 10.14 I get an unexpected exception when calling
"importlib.util.find_spec('py')" after importing "py". find_spec works as
expected before I import 'py'.
See the repl session below:
Python 3.7.2 (v3.7.2:9a3ffc0492, Dec 24 2018, 02:44:43)
[Clang 6.0 (clang-600.0.57)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import importlib.util
>>> importlib.util.find_spec("py")
ModuleSpec(name='py', loader=<_frozen_importlib_external.SourceFileLoader
object at 0x10a953fd0>,

submodule_search_locations=['/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/py'])
>>> import py
>>> importlib.util.find_spec("py")

This is with py version 1.7.0 installed (pip install py)
