How to install virtualenv by using pip in MacOS Hi

问题:

Command which i used to install virtualenv:-

sudo pip install virtualenv

Result:-

The directory '/Users/apple/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

sudo -H pip install foo
