Apparently it also works directly for me, but not with pip:
>>> import _cffi_backend
# extension module '_cffi_backend' loaded from '/opt/lib/python3.11/site-packages/_cffi_backend.cpython-311-arm-linux-gnueabi.so'
# extension module '_cffi_backend' executed from '/opt/lib/python3.11/site-packages/_cffi_backend.cpython-311-arm-linux-gnueabi.so'
import '_cffi_backend' # <_frozen_importlib_external.ExtensionFileLoader object at 0x763d6850>
I have also tried “pip -vvv”, which gives me additional error messages, but I can’t really figure it out either:
note: This error originates from a subprocess, and is likely not a problem with pip.
