In the case of permission denied error, you just need to go with this command.

sudo pip install virtualenv

sudo before the command will throw away the current user permissions error.

It's because the virtual environment viarable has not been installed.

Try this:

sudo pip install virtualenv
virtualenv --python python3 env
source env/bin/activate
pip install <Package>

or

sudo pip3 install virtualenv
virtualenv --python python3 env
source env/bin/activate
pip3 install <Package>
