ValueError：无法配置处理程序'file'：[Errno 2]没有这样的文件或目录：

Question

我是Python和Django的新手，目前正忙于通过www.djangoproject.com上的教程来学习自己。我正在使用PyCharm并在OS X El
Capitan上工作。我已经从github导入了一个项目，并基于Python 3.5.1为项目解释器创建了一个虚拟环境。在虚拟机中，我安装了django。

然后，我激活了虚拟机。

现在..我开始尝试在终端中像p一样执行简单的命令ython manage.py startapp deonapp，python manage.py runserver但是每次遇到下面粘贴的错误时，我都会错过什么？我似乎找不到/ log /目录？

Answer 1

由于某种原因，您没有日志文件的路径（/ Users / deon / Documents / PyCharmProjects / Developments
/ deonproject / log）。确保所有目录都存在（如果没有，请创建它们）并创建一个空的debug.log日志文件（以防万一）。

发生的事情是您的代码正在发生问题。处理程序会捕获此错误以将其保存到日志文件中，以便您可以对其进行分析。但是，尝试打开的日志文件的路径不存在。因此，在处理另一个异常期间会发生异常。
