Pip install to custom target directory and exclude specific dependencies

Question

I\'m looking for a method to use pip or similiar to install a list of python packages to a custom target directory (ex./mypath/python/pkgs/ ), but also exclude/blacklist

Answer 1

An approach that takes into account sub-dependencies is to first install the exclude.txt environment, then the req.txt environment, then check the diff and finally install that into the target directory.

Example using virtualenv that will work on GNU/Linux:

virtualenv tmpenv
source tmpenv/bin/activate

pip install -r exclude.txt
pip freeze > exclude-with-deps.txt
pip install -r req.txt
pip freeze > req-with-deps.txt
comm -13 exclude-with-deps.txt req-with-deps.txt > final-req.txt

pip install -r final-req.txt --no-deps -t pypkgs
