Detailed tutorial for installing pip on Windows

When developing in Python, we often use various third-party libraries. To install these libraries, we need to use the pip package management tool. However, installing pip under Windows is not as simple as under Linux. In this article, we will teach you step by step how to install pip on Windows, with detailed code examples.

Step 1: Download Python

First, you need to install Python. You can download the latest version of Python from the Python official website. On the download page, you need to select the version of your Windows operating system. After the download is complete, double-click the installation file and follow the wizard to install.

Step 2: Check whether the Python environment variable has been set

After the installation is complete, you need to check whether your Python is working properly. You can use the following command:

python --version

If you can see the Python version number, it means that Python has been installed successfully. If you see an error message, it means you need to add the path to Python to your system's environment variables:

1. Open "My Computer"->"Properties"-> "Advanced system settings".
2. Find the "Environment Variables" button and click it.
3. In "System Variables", find the variable named "Path" and double-click to edit it.
4. Add the Python installation path to the variable value, separated by semicolons.

For example:

C:Python36;C:Python36Scripts

Note: The path here needs to be modified according to your own installation path.

Step 3: Download get-pip.py

To install pip in Windows system, you need to download get-pip.py first. You can download the file at the following link: https://bootstrap.pypa.io/get-pip.py

The file is formatted as a Python script, so you can use Python commands to execute the file. After the download is complete, enter the directory on the command line and execute the following command:

python get-pip.py

This will download and install pip.

Step 4: Verify whether pip is successfully installed

After the installation is complete, you can use the following command to verify whether pip is successfully installed:

pip --version

If the version number appears on the screen , indicating that pip has been installed successfully.

In Windows systems, installing pip is actually very simple, just follow the above steps. However, if you find that errors occur when executing certain commands, it may be because your environment is not set up correctly. At this point, you can follow the steps below to solve the problem:

Step 5: Set up a proxy server

If you are using Python in an internal company environment, then it may not be able to connect to the server of the Python package. In this case, you need to set up a proxy server. In most cases, you need to open a terminal and enter the following command in the command line to set up the proxy:

set http_proxy=http://your-proxy-server:port

set https_proxy=https://your-proxy-server:port

Note: The proxy server and port here need to be modified according to your actual situation.

Step 6: Change pip source

pip downloads packages from https://pypi.org/simple/ by default. However, in some cases, this source may not work properly and you can replace it with another source.

For example, you can use the mirror source of Tsinghua University: https://pypi.tuna.tsinghua.edu.cn/simple/

Enter the following command on the command line to change the source:

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

So far, you have successfully installed pip on your Windows system and used this tool to download, install, update and manage Python packages. Hope this article helps you!
