You are keeping your virtualenv separate from your working tree, right?
I put mine in ‘/var/local/devel/$USER/virtualenvs/foobar/’ where
“foobar” is the specific virtualenv name.

This allows an arbitrary number of virtualenvs separate for each user
(‘/var/local/devel/$USER/’ is owned by each $USER), but all under one
directory tree where they can be treated specially for backup, cleanup,
permissions, or whatever.

Yes, you simply ‘pip install -r ./requirements.txt’ again. It does a
simplistic “is the package already installed at this version in the
currently-active virtualenv? If not, install it in that virtualenv”.

The environment variables that determine where the virtualenv lives are
managed by ‘/var/local/devel/$USER/virtualenvs/foobar/bin/activate’. You
don't have the packages cluttering up your working tree.
