运行Django开发服务器

Question

我正在尝试创建并运行一个项目。

我参考了以下文章：

https://docs.djangoproject.com/en/dev/intro/tutorial01/?from=olddocs

当我运行下面这个命令时：

C:\django\mysite>python manage.py runserver

就出现了这个错误：

Traceback (most recent call last):
  File "manage.py", line 14, in <module>
    execute_manager(settings)
  File "C:\Python27\lib\site-packages\django\core\management\__init__.py", line 438, in execute_manager
    utility.execute()
  File "C:\Python27\lib\site-packages\django\core\management\__init__.py", line 379, in execute
    self.fetch_command(subcommand).run_from_argv(self.argv)

我会这样做。试着使用 virtualenv。可能有一些旧的 Python 模块会以某种原因搞乱你的 Django。所以用 virtualenv 创建一个干净的 Python 环境，然后用 pip install 安装 Django。如果这样解决了问题，那肯定是你系统里的 Python 出了点小问题。
