virtualenv not active when run from a shell script

Question

When I run source venv/bin/activate in command line , it activates the virtualenv. However when run this via a shell script ./run.sh , I don't see the virtualenv being activated. Similar scripts used to work for me in the past , however I am not sure what I am missing now. I am running this is on a mac.

#! /bin/bash
source venv/bin/activate

Answer 1

When you are running source inside a script. It is running in a new environment. It won't get reflected in the parent shell.

$ cat run.sh
#! /bin/bash
source venv/bin/activate

It you need that to happen do, source your script,

source run.sh

Also, you won't need the shebang line :)
