ImportError: cannot import name 'ByteString' from 'typing' with Python 3.14 #28

Closed mxmlnkn closed 2 weeks ago

mxmlnkn commented 2 weeks ago

Python 3.14 has removed typing / will remove typing.ByteString. This leads to this error in my CI for 3.14.0-alpha.0:

/opt/hostedtoolcache/Python/3.14.0-alpha.0/x64/lib/python3.14/site-packages/PySquashfsImage/compressor.py:62: in __init__

My bad. I tried to find the code location but the log confused me and I completely forgot that I encountered this issue in another place 3 weeks ago: https://github.com/indygreg/python-zstandard/issues/238 This issue happens during the import zstandard line. So it is not an issue with this library directly.
