The "pip install pyhdf" fails with "hdfext_wrap.obj : error LNK2001"

Question

I'd like to use pyhdf in python3 with VS2022.OS is Windows10. I executed the command "pip install pyhdf" however I got this error message.

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for pyhdf
Failed to build pyhdf
ERROR: Could not build wheels for pyhdf, which is required to install pyproject.toml-based projects

Other modules can be installed so I think it's because the source code of pyhdf has something wrong with correspondence to VS, but I have no idea how to confirm and solve it. Any help would be greatly appreciated.

Answer 1

It's a linker error, did you configured Vistual Studio with your python correctly ?

And what is your python version, did you configure an pyenv by any chance ?
