If the tool cannot determine from where a package was installed, it will fail. This error can be ignored by supplying --ignore-errors flag. Any errors are turned into warnings that can be reviewed once the tool prints results.

To explicitly point to a site-packages directory, use the --site-packages option.

To get more information about this tool, issue --help.

FAQ

Q: The tool fails or I’m getting warnings similar to the one below and my output is missing some packages:

No provenance_url.json or direct_url.json found

A: You most probably don’t have pip with PEP-710 support. Please install pip with PEP-710 support, for example using this patch (experimental):

pip install git+https://github.com/fridex/pip.git@provenance-url
