问题
Someone's just asked me how to list all the virtual environments created with venv.
I could only think of searching for pyvenv.cfg files to find them. Something like:
from pathlib import Path
venv_list = [str(p.parent) for p in Path.home().rglob('pyvenv.cfg')]
This could potentially include some false positives. Is there a better way to list all the virtual environment created with venv?
NB: The question is about venv specifically, NOT Anaconda, virtualenv, etc.
回答1:
On Linux/macOS this should get most of it
find ~ -d -name "site-packages" 2>/dev/null
Looking for directories under your home that are named "site-packages" which is where venv puts its pip-installed stuff. the /dev/null bit cuts down on the chattiness of things you don't have permission to look into.
Or you can look at the specifics of a particular expected file. For example, activate has nondestructive as content. Then you need to look for a pattern than matches venv but not anaconda and the rest.
find ~ -type f -name "activate" -exec egrep -l nondestructive /dev/null {} \; 2>/dev/null
