Question

我启动我的Django项目，迁移我的数据库，之后运行我的服务器进行测试。

如果我在我的Python Django项目运行服务器...

(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 

我得到这个错误：

如何解决这个问题？

Answer 1

这可能是您的计算机名称的问题，而不是用户的名称。我以前经历过同样的问题。将计算机名称更改为英文名称后，问题得到解决。我认为这个问题是港口的名字。当我的计算机的名称是'书房台式计算机',, Django读取端口为'书房计算机：8000'并报告错误。

当我将计算机名称更改为'Gaara时，端口名称更改为'Gaara:8000'，但未返回错误。

您可以尝试按笔记本打开源文件。选择文件编码：UTF-8。然后将文件保存为新文件。重新加载新文件，您可以修复此错误。
