UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc4 in position 0: invalid continuation byte

Question

I start my Django project, migrate my databases, and after there I run my server for testing.

If I run the server in my Django project in Python...

(venv) C:\PR\djangogirls>manage.py runserver

Performing system checks...
System check identified no issues (0 silenced).
April 03, 2015 - 00:59:05
Django version 1.7.7, using settings 'mysite.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CTRL-BREAK

I get this error:

How do I fix this error?

Answer 1

It may be a problem with your computer name, not the user's name. I have experienced the same problem before. After I changed the computer name to an English name the problem was resolved. I think the issue is the name of the port. When my computer's name is '书房台式计算机 '，, Django reads the port as '书房计算机：8000 ' and reports an error.

When I changed the computer name to 'Gaara ' the port's name changed to 'Gaara:8000' and didn't return an error.

您可以尝试通过笔记本打开源文件，选择文件编码：UTF-8，然后将文件另存为新文件。重新加载新文件即可解决此错误。
