This error is because you are using an unrecognized version control system (VCS) when running the pip command in your terminal. VCS is a version control system used to manage software projects, such as git, Mercurial, etc. This error means that the VCS type you entered is not recognized by pip.
To resolve this error, you need to make sure you are using the correct VCS type and entering the VCS name correctly.
For example, if you want to install a package that uses Git version control, you should use the following command:
pip install git+https://GitHub.com/user/repo.git
or
pip install git+git://git.myproject.org/MyProject
If you want to install a package using Mercurial version control, you should use the following command:
pip install hg+Http://hg.myproject.org/MyProject
If you still don't know how to deal with this error, I suggest you check whether the project you want to install supports pip installation. And check whether the correct vcs type and address were entered during installation.
Yes, here are some examples:
Use Git installation package:
pip install git+https://github.com/user/package.git
Use Mercurial installation package:
pip install hg+http://hg.myproject.org/MyProject
Use Subversion Installation package:
pip install svn+http://svn.myproject.org/svn/MyProject
Use Bazaar installation package:
pip install bzr+http://bzr.myproject.org/MyProject
Use Fossil installation package:
pip install fossil+http://fossil.myproject.org/MyProject
Please note that the addresses for these commands are examples and the actual addresses may vary.
