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
Just to echo what @skytreader had previously commented, rmvirtualenv is a command provided by virtualenvwrapper, not virtualenv. Maybe you didn't have virtualenvwrapper installed?
rmvirtualenv
virtualenvwrapper
virtualenv
See VirtualEnvWrapper Command Reference for more details.
