Make virtualenv and activate it with shell script

  • 772

I want to make shell script that makes virtualenv, activates it, install some libraries and run python script with it.

But I have problem that I can't activate virtualenv in shell script unless i do "source script.sh" but then python3 doesn't work. How can I do something like this? 

#!/bin/bash
python3 -m pip install virtualenv
python3 -m virtualenv virtual
source virtual/bin/activate
pip install <some libraries>
python <filename.py>

I would like to do this without any global paths to python. I want it to work locally.

scripts command-line python bash virtualenv

    Working with Ubuntu (and most other Linux distros I’d say) it’s safe to use the absolute paths as Python is an essential component of the OS:

    /usr/bin/python   # or respectively
/usr/bin/python3

    If you don’t want to run the systemwide installed Python version, but rather the one first in the calling user’s PATH, instead use:

    /usr/bin/env python   # or respectively
/usr/bin/env python3
