I created an environment with the following command: virtualenv venv --distribute
virtualenv venv --distribute
I cannot remove it with the following command: rmvirtualenv venv
rmvirtualenv venv
You can remove all the dependencies by recursively uninstalling all of them and then delete the venv.
Edit including Isaac Turner commentary
source venv/bin/activate pip freeze > requirements.txt pip uninstall -r requirements.txt -y deactivate rm -r venv/
