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

This error typically occurs when there is an issue with generating metadata during the installation process. It is often not directly related to pip itself but rather with the package you are trying to install.

To troubleshoot this issue, you can try following steps:

1. Make sure you have the latest version of pip installed:

   pip install --upgrade pip

2. Check your internet connection to ensure it is stable and not causing any interruptions during the installation process.

3. Clear the pip cache and try again:

   pip cache purge
   pip install <package-name>

4. If you are installing a package from a private repository, ensure that your credentials are correctly configured.

5. If the issue persists, it may be worth considering updating or reinstalling the package that is causing the error.

If none of these solutions work, please provide more details about the specific package you are trying to install and any other relevant information, so that I can assist you further.
