I can't find this Chinese package （ My project is a virtual environment that runs on the server , You can also see from the error log ）
But I usually use it well , Why can't I use this bag suddenly

Since it can't be used , The small solution is to change to a Chinese package
stay base.py You can change it by setting the package name in （ In itself, these registrations exist django The path of ）

• Simplified Chinese ：zh-Hans
• Traditional Chinese ：zh-Hant

If not , Direct replacement of items Django package , Because maybe this package does not exist in this version （ It can be used without affecting the compilation of the whole project ）
（ Colleagues also changed their bags , Cause my side to affect , So my solution is to go back to that Django Version of ）

Find... Throughout the project LANGUAGE_CODE, Replace it with Django Some packages in the project

It can be replaced by zh-Hans , Recompile successfully

The other way is ： Replace Django edition , After all, some versions do not have these packages
