Question

I am trying:

brew install mysql
pip install mysql-python

I am getting this output:

What am I doing wrong and how can I install it?

Answer 1

The relevant error message is this:

error: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/_mysql.so

It can't copy to the target directory because of missing permissions.

You can either install it to the local user site directory using

pip install --user mysql-python

In this case it will only be available to the current user.

Or if you really need to install for all users on the machine, you can use sudo pip install mysql-python to install as root, but that is usually not recommendable.
