How to install modules in python

Python itself comes with some modules, which are very useful, but we did not install these modules when we installed python ourselves. In fact, the installation of these modules is very simple. Combined with the official installation tools, we can complete the installation process on the command line.

Before installing the module, you must first install setuptools. With setuptools, we need to start configuring the environment. Because you need to use the files in the Scripts folder in the python installation directory.

Go to the desktop, right-click on Computer--Properties

Click "Advanced System Settings"

Click "Environment Variables"

Scroll down in the system variables column, find PATH, double-click

First add a semicolon at the end;

Then enter "your python path"\Scripts

For example, my python installation path is D:\python2.7.6

Then I should enter D:\python2.7.6\Scripts

As shown in the figure

After setting up, you can directly use the command OK to install the module.

For example, if I want to install the PIL module, I only need to enter easy_install PIL

and press Enter

Start downloading

Installation successful
