Installation in MacOS fails without --user

[andresriancho]

Got this over email:

Just as an FYI, Mac owners will have to run pip install -r requirements.txt --user. The --user flag is necessary to get around the MacOS

System Integrity Protection, and without that flag you’ll get an obscure “Operation Not Permitted” error when attempting to install Nose.

Should document this issue in the main site to guide new users in their installation process.

Hola @andresriancho

That happens because you need to use the sudo -H before the installation on macOS, due to write permission issues on the folder where installs the packages.

When setting the --user flag, the installation goes to a directory under the current user's permission.

Definitely this is not a bug.
