Quick and dirty
- Install python3-virtualenvwrapper (via pip or via package manager)
- Export a workon directory:
export WORKON_HOME=/home/foursixnine/Projects/python-virtualenv -
source virtualenvwrapper
foursixnine@deimos:~/Projects> source virtualenvwrapper
virtualenvwrapper.user_scripts creating /home/foursixnine/Projects/python-virtualenv/premkproject
...
virtualenvwrapper.user_scripts creating /home/foursixnine/Projects/python-virtualenv/get_env_details
- mkvirtualenv newenv
foursixnine@deimos:~/Projects> mkvirtualenv newenv
created virtual environment CPython3.8.3.final.0-64 in 115ms

seeder FromAppData(download=False, pip=latest, setuptools=latest, wheel=latest, via=copy, app_data_dir=/home/foursixnine/.local/share/virtualenv/seed-app-data/v1.0.1)
activators BashActivator,CShellActivator,FishActivator,PowerShellActivator,PythonActivator,XonshActivator
virtualenvwrapper.user_scripts creating /home/foursixnine/Projects/python-virtualenv/newenv/bin/predeactivate

- By this point, you’re already inside
newenv:
(newenv) foursixnine@deimos:~/Projects>
- You can create multiple virtual environments and switch among them using
workon $envso long as you have sourcedvirtualenvwrapperand your$WORKON_HOMEis properly defined.
Real business
- Now, if you want to use vscode, remember that you will need to define properly
python.PythonPathfor your workspace/project (I’m new to this, don’t hang me in a public square ok?), in this case, my env is called linkedinlearningaiml
{
"python.pythonPath": "/home/foursixnine/Projects/python-virtualenv/linkedinlearningaiml/bin/python"
}
Now your python code will be executed within the context of your virtual environment, so you can get down to serious (or not at all) python development, without screweing up your host or polluting the dependencies and stuff.
PS: Since wanted to be able to run standalone python files, I also needed to change a bit my launch.json (Maybe this is not needed?)
"version": "0.2.0",
"configurations": [
{
"name": "Python: Current File",
"type": "python",
"request": "launch",
"program": "${file}",
"console": "integratedTerminal",
"cwd": "${fileDirname}"
}
]
}
And off you go, how to use python virtualenv inside vscode
Et voilà, ma chérie!
