How to use virtualenv in makefile

Question

I want to perform several operations while working on a specified virtualenv.

For example command

make install

would be equivalent

Answer 1

You also could use the environment variable called "VIRTUALENVWRAPPER_SCRIPT". Like this:

install:
    ( \
       source $$VIRTUALENVWRAPPER_SCRIPT; \
       pip install -r requirements.txt; \
    )

Answer 2

This is an alternate way to run things that you want to run in virtualenv.

BIN=venv/bin/

install:
    $(BIN)pip install -r requirements.txt

run:
    $(BIN)python main.py

PS: This doesn't activate the virtualenv, but gets thing done. Hope you find it clean and useful.
