Virtual Environments are a great way to isolate our dev tests, and after been using this in Windows also, work with them in the Raspberry Pi makes a lot of sense.
I’ll leave here the necessary steps to do this, however the full credit is based on some posts from Adrian Rosebrock and his amazing blog (see references).
Once we have everything updated in our Raspbian, let’s run the following command:
sudo pip install virtualenv virtualenvwrapper sudo rm -rf ~/get-pip.py ~/.cache/pip
Now we need to update the ~/.bashrc file using nano (not a big fan of VI )
And then add the following lines
# virtualenv and virtualenvwrapper export WORKON_HOME=$HOME/.virtualenvs export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3 source /usr/local/bin/virtualenvwrapper.sh
Now everytime we open a new terminal session, this commands will be applied and we will have our virtual environments up and running.
Next, source the bashrc file
And we can create a new virtual environment. Let’s create one named devOpenCV using python 3.
mkvirtualenv devOpenCV -p python3
We can enable and access the virtual environment with the workon command, and we will see the virtual environment as a prefix in our terminal
As we can see in the following screenshot, the virtual environment uses the latest Python 3 version, and just a few packages installed.
