I am trying to install packages via pip. Here some information:

OS = Ubuntu 15.10
python --version = 2.7.10
pip --version = pip 8.0.2 from /usr/local/lib/python2.7/dist-packages (python 2.7)

So far I have tried with scikit-learn, pyqrcode, and numpy using pip command, none of them was successfully installed. For example with numpy:

pip install numpy

The output is:

Any help? thank you

Try sudo pip install numpy - you can see at the bottom of that output above a 'permission denied' which tells you that your login doesn't have authority to do it, so adopting sudo extra powers fixes it.

  • Yes, It works with sudo. The package is installed. I also get: The directory '/home/diego/.cache/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. How to run it without sudo? – diegus Feb 22 '16 at 09:39
  • sudo chown -R diego:diego .cache should fix it - it shouldn't do that! The -H option just makes it use your home as it's home. This tends to be the default (& clearly was on your system) so you can ignore that part. – Mark Williams Feb 22 '16 at 10:05

    Using sudo to pip install is not recommended. – vaer-k Aug 24 '17 at 22:19
