This work like install to submachine

First of all you need virtual environment library. Then create one. This work by mounting to specific folder you name in this case it is ./foo

$ pip3 install virtualenv
$ python3 -m venv foo

Then you can activate this virtual environment with activate binary inside bin subfolder.

$ source ./foo/bin/activate

Then you install anything just like it is the clean new machine

(foo) $ pip3 install robotframework

To exit this virtual world you can do that by running

deactivate

Issue: This environment is externally managed

This is error when you forget to activate next time you use the machine. You can do it by:

source /path/to/venv/bin/activate
