How can I install from a git subdirectory with pip?

Question

I have a git repository with many folders, one of them being a python module installable with pip, like this:

repo.git/
repo.git/folder1/
repo.git/folder2/
r

It's been already stated in one of the comments under the correct answer, but just to highlight this issue: when executing this from Linux command line, you must escape the &-character since ampersand is telling the command line to run a command in background:

git+https://git.repo/some_repo.git#egg=version_subpkg\&subdirectory=repo

Notice the backslash before the ampersand. The escaping behaviour might depend on the Linux distro; I'm not an expert.
If you ignore this, you might run into a cryptic error like the following:

bash: (...) command not found
