Five simple ways to change pip sources to solve the problem of slow download speeds

Selected five pip source changing methods to easily deal with the problem of slow download speed

In recent years, Python has become more and more widely used, and more and more of developers started using Python to write various applications. In the process of Python development, it is a very common operation to use pip to install various dependency packages. However, due to the limitations of the domestic network environment, pip download speeds often result in slow download speeds, which brings a lot of trouble to developers. In order to solve this problem, this article will introduce five commonly used pip source changing methods to help developers easily solve the problem of slow download speeds.

Method 1: Use domestic mirror sources
Many large domestic Internet companies provide Python mirror sources. By configuring and using these mirror sources, the download speed of pip can be greatly improved. For example, Alibaba Cloud provides a Python mirror source: http://mirrors.aliyun.com/pypi/simple/, which can be used by modifying the pip configuration file. The specific steps are as follows:

1. Open the pip configuration file. Under the Windows system, it is C:Users username pippip.ini. Under the Linux system, it is ~/.pip/pip.conf;
2. Add the following content in the configuration file:
   [global]
   index-url = http://mirrors.aliyun.com/pypi/simple/

Method 2: Use Tsinghua University University mirror source
Tsinghua University also provides a Python mirror source: https://pypi.tuna.tsinghua.edu.cn/simple/, which can also be used by modifying the pip configuration file. The specific steps are as follows:

1. Open the pip configuration file. Under the Windows system, it is C:Users username pippip.ini. Under the Linux system, it is ~/.pip/pip.conf;
2. Add the following content in the configuration file:
   [global]
   index-url = https://pypi.tuna.tsinghua.edu.cn/simple/

Method 3: Using Douban Source
Douban also provides a Python mirror source: https://pypi.doubanio.com/simple/, which can also be used by modifying the pip configuration file. The specific steps are as follows:

1. Open the pip configuration file. Under the Windows system, it is C:Users username pippip.ini. Under the Linux system, it is ~/.pip/pip.conf;
2. Add the following content to the configuration file:
   [global]
   index-url = https://pypi.doubanio.com/simple/

Method 4: Use Huawei Cloud Image Source
Huawei Cloud also provides a Python mirror source: https://mirrors.huaweicloud.com/repository/pypi/simple/, which can also be used by modifying the pip configuration file. The specific steps are as follows:

1. Open the pip configuration file. Under the Windows system, it is C:Users username pippip.ini. Under the Linux system, it is ~/.pip/pip.conf;
2. Add the following content in the configuration file:
   [global]
   index-url = https://mirrors.huaweicloud.com/repository/pypi/simple/

Method five: Use self-built mirror sources
If the above mirror sources cannot meet the needs, developers can also build their own mirror sources. The specific steps are as follows:

1. Install the Flask package: pip install flask;
2. Create a Python script named mirror.py and write the following code:

from flask import Flask, redirect
app = Flask(__name__)

@app.route("/simple/")
def index(filename):

return redirect("http://pypi.python.org/simple/" + filename)

if name == "__main__":

app.run()

3. Run mirror.py: python mirror.py;
4. Modify pip Configuration file, set index-url to http://localhost:5000/simple/.

Summary:
By using the above five pip source changing methods, developers can easily deal with the problem of slow download speeds. According to your actual needs, choosing the mirror source that suits you can provide developers with a faster pip download experience.
