Ok. If using less common choices, some documentation will not apply 
directly ;-)

https://docs.python.org/3/tutorial/venv.html#creating-virtual-environments 
hints that you might be able to source activate.csh instead. Or just use 
bash for this.

No, it is not system wide. When the virtualenv is activated, it will 
modify PATH to start with ../kallithea-venv/bin/ where it's own pip (and 
python) "binaries" are available - they will work inside the virtualenv, 
not globally.

Since you are not running as root, there is also no way it could have 
modified anything system wide.

Are you still in the directory of the kallithea source (with a setup.py)?

No, it is not impossible. You just didn't activate the virtualenv - thus 
the later commands doesn't work as intended. Either use bash, or 
activate your csh.

I suggest creating /srv/kallithea as root, and chown it to the kallithea 
user. (I am trying to tweak the documentation based on your input and 
already had some draft changes to this.)

Other than creating the installation directory (which could be 
elsewhere), there should not be any global or .local changes. Just 
active the virtualenv first (or run binaries in the virtualenv's bin 
directory).
