Tsinghua Mirror Tutorial: How to install the Python library through Tsinghua Mirror, specific code examples are required

Introduction:
In Python development, third-party libraries are often needed to expand your functionality. However, due to limitations of the network environment, sometimes we cannot install the required libraries directly from official sources. At this time, Tsinghua Mirror becomes a good choice. This article will introduce how to use the Tsinghua mirror to install the Python library and demonstrate it through specific code examples.

1. What is Tsinghua Mirror?
Tsinghua Mirror is a set of domestic public software mirror sources developed by Tsinghua University. This mirror source provides downloads of many common open source software, frameworks and libraries, including Python, Java, Node.js, etc. By using Tsinghua mirrors, we can speed up software installation and improve development efficiency. In Python development, we can install the required libraries by specifying the Tsinghua mirror source.

2. Steps to install Python library using Tsinghua mirror
The following takes the installation of one of the most commonly used Python libraries - the requests library as an example to introduce how to install the Python library through Tsinghua mirror.

1. Install pip tool
   Before using the Tsinghua image to install the Python library, we first need to install the pip tool. pip is Python's package management tool, used to install and manage Python packages.

Execute the following command in the command line window to install:

python -m ensurepip --default-pip

2. Set the Tsinghua mirror source
   Execute the following command in the command line window to set Tsinghua mirror source:

   pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

3. Install the requests library
   Next, we can use the Tsinghua mirror to install the requests library. Execute the following command in the command line window:

   pip install requests

   After the installation is complete, we can use the requests library in our Python script.

4. Verify the installation result
   Enter the following code in Python interactive mode:

   import requests
   print(requests.__version__)

   If the version number of the requests library is output, the installation is successful.

3. Tsinghua mirror source for other commonly used software
In addition to the Python library, Tsinghua mirror source also provides downloads of other commonly used software. Commonly used Tsinghua image sources and their setting commands are as follows:

1. Node.js

   npm config set registry https://registry.npm.taobao.org

2. Java
   in the ~/.bashrc file Add the following environment variables:

   export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
   export JAVA_HOME=/usr/local/jdk
   export PATH=$PATH:$JAVA_HOME/bin
   export JAVA_OPTS="-Xms1024m -Xmx1024m -XX:PermSize=256M -XX:MaxPermSize=1024M"

3. Ruby

   gem sources --add https://gems.ruby-china.org/ --remove https://rubygems.org/
   gem sources -u

##4. Summary

By using the Tsinghua mirror source, we can install faster Required Python libraries to improve development efficiency. This article introduces the steps to install the Python library using Tsinghua mirror and gives specific code examples. In addition to the Python library, we can also use the Tsinghua image to install other commonly used software. I hope this article will be helpful for installing Python libraries using Tsinghua images.
