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

Encountered error while generating package metadata.

See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

I've tried python 3.7.4 64bit、3.7.4 32 bit、 3.9.10 64bit but all have the same error.
Can you check out what's the problem?

Thank you

Did you find a solution to this problem?

I am currently on 0.18.15 and tried to upgrade to the latest version and found exactly the problem you have above. I have upgraded a number times with older versions and never had a problem. It seems the installation process must have changed. I did look on the internet for potential solutions, there is some talk of similar issues but its not really an area I have much experience in, and nothing seemed that trivial.

Ok, I hope it works for now.
And yes, the new-school build is still WIP.

I have just tried this again but I still get an issue:

  pyxcp/recorder/lz4.cpp(117): fatal error C1083: Cannot open include file: 'lz4.h': No such file or directory

I also notice an error earlier on in the process (not sure if this really a problem though):

  running asamkeydll                                                                            
  Building pyxcp/asamkeydll.exe failed: '[WinError 2] The system cannot find the file specified'

I have not used or needed to build this dll, since I have 64 bit seed and key dll's already.
