我刚刚开始学习 Django，并严格按照他们的教程进行操作。我尝试设置网站 3 次，每次都遇到相同的错误（在标题中）。

再次，按照他们的官方教程进行操作。我在教程 2，我应该访问管理页面。当我有DEBUG = False 时，我会在标题中收到错误消息，这就是控制台输出的内容：

deusdies@galaksija:~/Documents/djangosites/testing$ python manage.py runserver

这是DEBUG = False。使用DEBUG = True，我得到标准的“它有效！”页面，即使我访问 /admin/ URL，或者页面上的任何其他 URL。

这是我的settings.py：

SO 其他地方的一些人建议我创建一个 500.html 模板并查看错误是什么 - 只是我不知道该怎么做。

【问题讨论】：

您的设置不完整，您的模板没有路径，这就是您收到该错误的原因这是由 django-admin.py 自动生成的 ... 【参考方案1】：

在观看了一个较旧版本的 Django 的 YouTube 视频教程后，我找到了解决问题的方法。我不得不取消注释urls.py 文件中的某些行（特别是与管理员相关的行），现在它可以工作了。我很困惑为什么在官方教程中忽略了这个......

【讨论】：

除了这里的docs.djangoproject.com/en/1.4/intro/tutorial02/…，它说“编辑您的 mysite/urls.py 文件并取消注释引用管理员的行 - 总共有三行需要取消注释。”然后显示行的突出显示版本。这不是从主页链接的教程。我跟着这个：我去了 djangoproject.com，点击我下载的“下载最新版本”，然后点击那个页面上一个标题为“安装指南”的链接，它把我带到了docs.djangoproject.com/en/dev/intro/install。如果你问我，提供一个版本供下载，然后链接到另一个版本的教程，这很愚蠢。至少他们可以让它更加突出一点。这是一个非常好的观点，可能值得开票。同意。因此，我在 djangoproject.com 上创建了一张票。谢谢你的帮助，马克。文档一直使用 cookie 来指示您正在使用文档的哪个分支。如果“安装指南”将您指向 dev 而不是最新的 stable 分支，则意味着您在过去的某个时间已经切换到 dev。如果缓存为空，访问 djangoproject.com 将指向 1.4 文档。【参考方案2】：

在控制台中写入：“manage.py syncdb”，它应该可以工作。它对我有用
