Installing PIP for Python

without comments

If you’re on a Mac running macOS Sierra, you can install PIP to add packages. PIP stands for either of the following:

  • PIP installs Packages
  • PIP installs Python

You use the following to install the PIP utility:

sudo easy_install pip

It should return the following:

After you install PIP, you can use PIP to add custom packages to the Python environment. The

sudo pip install easygui

You get the following warning and installation:

The directory '/Users/michaelmclaughlin/Library/Caches/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.

Installing collected packages: easygui
Successfully installed easygui-0.98.1

After installing the easygui Python library, you can change to the root directory to confirm the installation of the easygui Python library with the following command:

find . -name easygui* 2>/dev/null

It returns the following:

./Library/Python/2.7/site-packages/easygui
./Library/Python/2.7/site-packages/easygui/easygui.py
./Library/Python/2.7/site-packages/easygui/easygui.pyc
./Library/Python/2.7/site-packages/easygui-0.98.1.dist-info

You can connect to Python 2.7 in a Terminal session. Then, you use the easygui library to run a Hello World! message box with the following commands in the Python shell:

import easygui
easy gui.msgbox("Hello World!")

It will raise the following image:

Hopefully, this helps a few folks.
