Python 3.11 and npm 6 (Node.js 14.x) does not support rebuilding from source

[mmomtchev]

pymport cannot be rebuilt from source with Python 3.11 and npm 6.

Old versions of node-gyp are not compatible with Python 3.11.

nodejs/node-gyp#2219

There is no solution to this problem except to upgrade npm

The error message is:

The U file mode was removed in Python 3.11 because it had no effect so the U can merely be removed.

Why use npm 6 when npm 9.2 is available?

[mmomtchev]

This is exactly why this issue has a wontfix label - if you have npm 6 and Python 3.11 you cannot build pymport and the only solution that makes any sense is to upgrade.
