Question

我是Python和Django的新手，目前正忙着通过www.djangoproject.com上的教程学习自己。我正在使用PyCharm并在OS X El Capitan上工作。我从github导入了一个项目，并为基于Python 3.5.1的项目解释器创建了一个虚拟环境。在vm我安装了django。

然后我激活了vm。

现在..我开始尝试在终端中执行简单的命令，如p ython manage.py startapp deonapp和python manage.py runserver，但每次我收到错误，我粘贴在下面..我错过了什么？我似乎无法找到/ 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（如果不存在，创建它们）并创建一个空的debug.log日志文件（以防万一）。

您的代码发生了一些问题。处理程序捕获此错误以将其保存到您的日志文件中，以便您可以对其进行分析。但是，它尝试打开的日志文件的路径不存在。因此，在处理另一个异常时会发生异常。

Answer 2

万一有人得到它有用：在我的情况下，错误是由权限问题触发的。一旦我更改权限并让应用程序用户在文件夹中写入，问题就解决了。

ValueError：无法配置处理程序＆＃39;文件＆＃39;：[Errno 2]没有这样的文件或目录：
