python - pip install django error

Question

I'm trying to install django using pip in Terminal.

I always get an exception, however. The last error is always "permission denied", and I do not understand why. Any help is appreciated.

Log:

pip install django
You are using pip version 7.1.0, however version 8.1.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

sudo pip install django 

The error tells you that you can't access a directory (you don't have enough permissions), so you can gain root access via sudo to get the permissions.
