Answer 2

I think a solution with a separate virtualenv environment will suit you:

1. Install virtualenv on your system (the following is an example for Linux).
2. Create a new environment with a console command
   virtualenv ~/my_env_for_work -p /usr/bin/python2.7
3. Activate the environment
   source ~/my_env_for_work/bin/activate
4. Install the required package.
