`import musictree` fails with UnicodeDecodeError

automaciej commented 1 year ago

I'm testing on Debian 11, pypy.

$ pypy --version
Python 3.7.10 (7.3.5+dfsg-2+deb11u2, Nov 01 2022, 20:16:36)
[PyPy 7.3.5 with GCC 10.2.1 20210110]

I installed pypy-dev, pypy3-dev (required to find Python.h) and after the installation I got this:

$ python
Python 3.7.10 (7.3.5+dfsg-2+deb11u2, Nov 01 2022, 20:16:36)

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 311: ordinal not in range(128)

I didn't do a deeper dive on this, just recording that there seems to be a problem.

Thanks for your comment. I'm afraid musicscore2 do not run under your python version (3.7). You need at leat version 3.9.

Thanks, I can confirm that this works with Python 3.9:
