Edit: FIXED!
Just had to chown the .cache directory
I\'ve tried the virtualenvwrapper docs instructions, I\'ve tried this guy\'s instructions as well as these...
you need to change the owner of directory of pip.
run chown -R <user>:<group> /home/aweeeezy/.cache/pip.
I think that if you do that pip install numpy --no-cache-dir it will work.
If you run pip --help you will find:
--no-cache-dir Disable the cache.
Hope that it can help to someone in the future.
