Suddenly got error about missing libraries "Unable to load any of the following libraries"

[andkirby]

It was working fine, but for some reason, I started getting this error.

ImportError: Unable to load any of the following libraries:libhidapi-hidraw.so libhidapi-hidraw.so.0 libhidapi-libusb.so libhidapi-libusb.so.0 libhidapi-iohidmanager.so libhidapi-iohidmanager.so.0 libhidapi.dylib hidapi.dll libhidapi-0.dll

It happens on in line with import hid.

Tried to uninstall/install hid package. The same.

Why?

OS: Windows 11
CLI: Git bash
Python: 3.9.9 (venv)

Had the same, don't know how to fix it but found a workaround: load the hidapi DLL before importing the hid library.

import os, ctypes
ctypes.CDLL('/path/to/hidapi.dll'))```

FreeBSD package has a local patch for this issue:

I'm having this same issue on Windows. I tried reinstalling hidapi, to no avail.

The workaround involving ctypes doesn't work, either, because I don't have a hidapi.dll. I know this is suspicious, but the only file that comes from installing hidapi that seems able to do any work is hid.cp311-win_amd64.pyd.

What I remember how I did solve this issue, seem I had to install different packages, and it didn't ask about this library anymore.

Same here, honestly 😆
