ModuleNotFoundError: No module named 'swig' on CentOS9 when install M2Crypto

[Fenglinhsh]

I get below printout when running pip install M2Crypto, seems swig could not be found, but actually it was installed sucessfully, I can found them in path /usr/local/bin/. What should I do to resolve this issue?

  [end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
