Music21 AttributeError: module 'importlib' has no attribute 'util'

I'm trying to get started using music21 in python. I've imported the package into PyCharm but when I use the line:

import music21

at the start of my file, it gives me:

Traceback (most recent call last):
  
File "C:/Users/Miles/Documents/Miles/Uni/Coding/Music21/Start.py", line 1, in <module>
    import music21
  
File "C:\Users\Miles\Documents\Miles\Uni\Coding\Music21\venv\Environment\lib\site-packages\music21\__init__.py", line 169, in <module>
    
from music21 import base  # noqa: E402
  
File "C:\Users\Miles\Documents\Miles\Uni\Coding\Music21\venv\Environment\lib\site-packages\music21\base.py", line         119, in <module>

loader = importlib.util.find_spec(modName)
AttributeError: module 'importlib' has no attribute 'util'

It works fine when I try to run it from the python console, and I'm using python 3.7 and music21 version 6.5 which should be compatible so not sure where I'm going wrong.

Solution

  • Fixed in the unreleased version (current development branch on GitHub).
