How to run virtual environment from shell script?

Question

I am trying to setup my project environment from a shell script on ubuntu so that I can skip basic setup every time.

I use my virtual environmet cv using the command workon cv .

But I am having trouble doing so using a shell script. I tried the the script

#!/bin/bash

workon cv

But I get the error

workon: command not found

I try to list all the venv I have

pran@pran-HP-65-Notebook-PC:~$ lsvirtualenv
cv
==


virtual-py2
===========

Also, I thought of locating it

(cv) pran@pran-HP-65-Notebook-PC:~/.virtualenvs$ l
cv/               postdeactivate     preactivate*      prermvirtualenv*
get_env_details*  postmkproject*     predeactivate     virtual-py2/
initialize        postmkvirtualenv   premkproject*
postactivate      postrmvirtualenv*  premkvirtualenv*

How can I do it?

Answer 1

You cannot execute workon command outside of Python virtual environment.

If it is not what you need then please clarify your requirements for a project environment.

Answer 2

I found the solution:

My venv was located in .virtualenvs . So, I put the command in the bash file start.sh (meant to be executed before working on my project).

#start.sh
source ~/.virtualenvs/cv/bin/activate

And run it using

$ source start.sh

It works perfectly
