The simplest way to install third-party libraries in Python

First, the preparatory work

(It will be convenient to do only one preparation work)

1. Install Pip

(1) Download Pip to D:\download

Pip:https://pypi.python.org/pypi/pip#downloads

(2) Extract to the current directory after downloading;

(3) "win+r" into cmd; Enter the following code, in turn:

C:\USERS\ADMINISTRATOR>CD D:\download\pip-9.0.1C:\Users\Administrator>D:
D:\download\pip-9.0.1>python setup.py Install

(4) Configure environment variables:

Add the installation path to the PIP in path: The script folder under the Python installation path

(5) Complete

Re-"win+r" into CMD; run the following code directly:

Run: Pip-v or Pip--version, showing the version information of the PIP

2. Installing Wheel

(For offline installation of downloaded WHL files)

"Win+r" into CMD; run the following code directly:

Pip Install Wheel

Ii. installation of third-party libraries

1. Online Installation

Run directly in the CMD window: Pip install package name, such as Pip install requests

Note: This method will automatically download the third-party library, after the installation is completed and will not be deleted, if you want to delete the default download path to it manually deleted;

Win7 default path://AppData may be the default path for the hidden folder \ \ user \ (your user name) \appdata\local\pip\cachelinux:~/.cache /pip

In fact, there is no need to delete the cache, add--no-cache-dir can disable caching

2. Offline installation

(1) Download

In http://www.lfd.uci.edu/~gohlke/pythonlibs/download the. whl file for the required library, note that the cp** in the file name should match the installed version. If you install Python2.7, you should download the corresponding cp27. WHL file

(2) Installation

Run: Pip install **.WHL, if wheel is installed.

3. Unzip the installation

Rename the. WHL suffix to zip, unzip, and put the extracted folder into the python/lib/site-packages.
