Speed ​​up the Python development process: master pip source changing skills and improve efficiency

In the Python development process, it is often necessary to use pip to install and manage third-party libraries. However, due to the instability of the domestic network environment and the speed limit of the external network, many developers You may encounter slow pip download speeds, seriously affecting work efficiency. To address this problem, we can learn how to master the pip source swap method to improve the efficiency of Python development.

1. Pip source change method

1. Temporary source change

When using the pip command, you can use the parameter "-i" to specify a domestic source, for example:

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple flask

Here we use Tsinghua source to install the flask library, which can speed up the download speed.

2. Permanent source change

We can also make the source change operation permanent, so that every time pip is used, the source we specify will be used by default. The specific method is to create a pip directory in the user's home directory, create a new pip.conf file in it, and then write the new source address into the file. For example:

Under Windows system, you can use the following command in the command line to create the pip directory:

mkdir %APPDATA%pip

Then, enter the directory to create pip. conf file and write the new source address:

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple

After saving , the next time you use pip to install the library, it will automatically use Tsinghua source to download, and the speed will be much faster than before.

2. Usage Example

Below we use the installation of pyecharts library as an example to demonstrate how to use the above method to improve pip download efficiency.

1. Temporary source change

We can use the following command on the command line to install the pyecharts library, plus -t to specify the installation directory:

pip install -i https ://pypi.tuna.tsinghua.edu.cn/simple -t D:projectspyecharts pyecharts

Note that here we use the Tsinghua source and save the installation file to the D:projectspyecharts directory.

2. Permanent source change

If we want pip to use Tsinghua source by default to download the library, we can enter the command line and type the following command:

mkdir %APPDATA%pip
echo [global] > %APPDATA%pippip.conf
echo index-url = https://pypi.tuna.tsinghua.edu.cn/simple >> %APPDATA%pippip.conf

Here we create the pip directory in the user's home directory, create a new pip.conf file in it, and then write the Tsinghua source address into the file.

Next, enter the following command on the command line to install the pyecharts library:

pip install -t D:projectspyecharts pyecharts

At this time, pip will automatically use our settings Download from a designated Tsinghua source, so the speed will be faster than before.

To sum up, in response to the problem of slow pip download speed, we can learn to use pip source swap method to improve development efficiency. By mastering the methods of temporary source change and permanent source change, we can greatly shorten the download time of third-party libraries and improve the efficiency of Python development.
