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

Faced with a similar problem, and using a running bash shell I managed to exclude specific packages with

pip install $(grep -ivE "pkg1|pkg2|pkg3" requirements.txt)

where pkg1 and so on are the names of the packages to exclude.
