is it correct to configure virtualenv in that location (manjaro)

I'm using the "Vanessa" manjaro system. I need to use virtualenv but it is not starting to create the environment.export. I'm following this very common pattern on linux-based systems. **sudo nano ~/.bashrc** export WORKON_HOME=~/.virtualenvs source /usr/bin/virtualenvwrapper.sh **all files are in that location** **ls /usr/bin/vi** vi@ virtualenv* virtualenvwrapper.sh* view@ virtualenv3* visualinfo* vigr@ virtualenv-clone* visudo* vipw* virtualenvwrapper_lazy.sh* but nothing happens, the script does not start and the **workon** command does not appear
