OSError: cannot load library

[Fograd]

Hey there, first of all, I am not a programmer. I just need to run a program that has been sent to me and uses the soundfile library.

I have installed soundfile using pip (I am on Mac M1, using PyCharm as IDE, python 3.10.2) but when I run my program, I get this error:

File "/Users/mehradmansoubi/PycharmProjects/multi/venv/lib/python3.10/site-packages/soundfile.py", line 162, in <module> _snd = _ffi.dlopen(_os.path.join( OSError: cannot load library '/Users/mehrad/PycharmProjects/multi/venv/lib/python3.10/site-packages/_soundfile_data/libsndfile.dylib': dlopen(/Users/mehrad/PycharmProjects/multi/venv/lib/python3.10/site-packages/_soundfile_data/libsndfile.dylib, 0x0002): tried: '/Users/mehrad/PycharmProjects/multi/venv/lib/python3.10/site-packages/_soundfile_data/libsndfile.dylib' (no such file), '/usr/lib/libsndfile.dylib' (no such file)

where can I get this "libsndfile.dylib" and I am assuming, other missing files to get it to work? I read in some other issue that the problem is from pip 20. I downgraded it to a lower pip and it still does not work.

Could anyone please, in a simple non-programmer language explain what the issue is and how I can resolve it? thank you <3

There's a fix for this in #310, but I haven't gotten around to publishing the bugfix yet. There's a related bugfix in #322 that needs to be included, too.

any update to this? I just raan into the same thing with python 3.10.8

You should have an up-to-date pip and wheel, and then pip install soundfile, to get the proper wheel. Otherwise, install libsndfile using e.g. brew.

[williamarchbold]

is 0.11 soundfile the latest?
