I can't get peewee to install using the command 'pip install peewee' in my terminal on Mac.

This is because you are trying to install Peewee to a global directory that you do not have permission to modify. If you'd like to install peewee globally like this, you can use a sudo command to do so. 

sudo pip install peewee

This will prompt you to authenticate before allowing you to override the permissions issues.

In practice, you will rarely install packages like peewee globally in this manner, you will use a virtual env to create various development environments. However, for learning purposes installing this globally works just fine.

Thanks for the help Brian! I ended up doing sudo pip3 install peewee because it was only installing for older versions of Python on my computer!
