Configure domestic mirror sources

Source of problem

This error persists today when installing the xlutils package using pip install xlutils

ReadTimeoutError: HTTPSConnectionPool (host='files.pythonhosted.org', port=443): Read timed out.

This may be due to the fact that when some libraries are installed in this way, they will be downloaded from foreign mirror sources, resulting in a response timeout.

Too heart-wrenching, sometimes want to use a library, but have been unable to download it, there is no way to worry! How to solve the problem?

Configure domestic mirror sources

Here, before formally talking about the knowledge points, I would like to introduce to you a few commonly used mirror sources. It doesn't matter if you don't know, just understand.

Temporary use of "domestic Mirror Source" by ①

If you don't want to configure the mirror source, you just want to temporarily use the domestic mirror source and install a library. At this point, you can enter the following command:

# download directly, slow pip install pandas # download using domestic mirror sources, fast pip install pandas-I https://pypi.tuna.tsinghua.edu.cn/simple/

Notice the difference between the two, except that the-I parameter is used to specify the mirror address.

This method is one-time, and you need to do this all the time if you want to download other libraries.

② permanently uses "domestic Mirror Source"

Is there a way to solve this problem once and for all? This is what we are going to talk about. We will tell you about it on the platform of linux and windows respectively.

For the linux platform:

First, create a directory pip and a pip.conf file under the directory using the following command.

# create a directory mkdir ~ / .pip # change to this directory cd ~ / .pip # in this directory, create a file touch pip.conf

Next, open the pip.conf file using the following command.

Sudo vi / .pip/pip.conf

Then, write the following into it.

[global] index-url = https://pypi.tuna.tsinghua.edu.cn/simple[install]trusted-host = https://pypi.tuna.tsinghua.edu.cn # trusted-host this parameter is to avoid trouble, otherwise it may prompt you not to be trusted

Then, save and exit. If you are not familiar with the linux command, go down and learn by yourself.

For the windows platform:

First, you need to create a new folder pip under the user user directory

Next, under the pip folder, create a pip.txt text file, and then change the suffix from "txt" to "ini"

Finally, write the following into it

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

After the modification is completed, save it.

Start cmd again, use the "pip install library name" to install the related libraries, and you can download from domestic sources by default.
