安装时一直未配置python环境变量
程序也一直放scripts目录下运行
今日得limodou兄指点将tools/scripts目录 lib目录设置环境变量
然后将django一步一步学习中的newtest包移动到了python24根目录下.
但此时在运行一步一步学习django中的一些例子时就出现了问题
helloworld能运行  加法(add)能运行
但http://127.0.0.1:8000/login/
 http://127.0.0.1:8000/wiki/
都不能运行了..
报错是(login的):

OperationalError at /login/

Request Method:GET
Request URL:http://127.0.0.1:8000/login/
Exception Type:OperationalError
Exception Value:no such table: core_sessions

# middleware, and if the exception middleware returns a

for middleware_method in self._exception_middleware:

Wiki的报错为:

Request Method: GET
Request URL: http://127.0.0.1:8000/wiki/
Exception Type: OperationalError
Exception Value: no such table: wiki_wikis
Exception Location:
