Question

I have following setup in my ubuntu virtual environment

pip list argparse (1.2.1) pip (1.5.4) setuptools (20.10.1) wsgiref (0.1.2)

I want to install setuptools 18.2 as its a project requirement. Please advise how I can do this

Answer 1

I just tested it, it looks like just doing pip install setuptools==18.2 should do it.

$ pip install setuptools==20.10.1
