Editor to share with you how the Python module is always installed failed or slow, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Preface

As we all know, when third-party modules are installed in python, commands are entered into CMD.

1pip install module name

Because the default download module address of python is a foreign website, the download speed of installing python module will be very slow.

It takes half an hour to download a 7mb module, which certainly won't work, and it will appear when you install it.

Time out reported an error

So you can use the domestic mirror source installation.

1 Tsinghua: https://pypi.tuna.tsinghua.edu.cn/simple2 Ali Yun: http://mirrors.aliyun.com/pypi/simple/3 University of Science and Technology of China https://pypi.mirrors.ustc.edu.cn/simple/4 Huazhong University of Science and Technology: http://pypi.hustunique.com/5 Shandong University of Technology: http://pypi.sdutlinux.org/ 6 Douban: http://pypi.douban.com/simple/

Installation commands such as:

1pip install-I https://pypi.doubanio.com/simple/-- trusted-host 2pypi.doubanio.com module name

In this way, the download speed will be very fast.

But

Who remembers such a long website? do you have to find a mirror source website every time you install it?

This is too inconvenient, so we can configure it to use mirror source installation automatically every time pip is installed.

For example:

Although I installed the module in pip instal pyqt5, it is still very fast.

Configuration file

Pip.ini

1 [global] 2timeout = 60003index-url = http://pypi.douban.com/simple4trusted-host = pypi.douban.com

Copying the pip folder in the file to the system's personal directory (C:\ Users\ user name) will solve the problem.
