OSError: sndfile library not found using ctypes.util.find_library #468
Description
I tried installing python-sound-file by running python setup.py install and then installing modules until it worked
But when I run my program, I get
Traceback (most recent call last):
File "C:\python13\Lib\site-packages\soundfile.py", line 192, in <module>
import _soundfile_data # ImportError if this doesn't exist
^^^^^^^^^^^^^^^^^^^^^^
ModuleNotFoundError: No module named '_soundfile_data'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "C:\python13\Lib\site-packages\soundfile.py", line 201, in <module>
raise OSError('sndfile library not found using ctypes.util.find_library')
