这是什么意思？我该如何解决？

【问题讨论】：

看起来应用程序无法读取正在写入日志的文件。为什么要将它们保存到/tmp？
你说我在 /tmp 中保存了什么？事实上，我不确定你在说什么。但我认为可能与我的 wsgi 文件中写的“os.environ ['PYTHON_EGG_CACHE'] = '/tmp'”有关。
我按照教程在 wsgi 文件中写了 os.environ ['PYTHON_EGG_CACHE'] = '/tmp'。 :)
self.addLogFile("/tmp/masterLog.log", "DEBUG")。您的应用已配置为将某些内容记录到 /tmp/
egg缓存仅用于解压egg文件。您可以将其设置为 HOME 的子目录，就可以了。

【解决方案1】：

通常这可能是渲染时的文件权限问题

对您的模板目录执行chmod 777 -R。

或者你升级你的 django 版本了吗？

【讨论】：

-1。向所有人开放您的模板目录？坏主意。
我的意思是开发环境我说777后我们可以更改它的服务器执行权限
你没有这么说。即便如此，这也是个坏主意。 Web 服务器将以 you 身份运行。为什么你需要对模板目录的写权限，为什么每个人都需要写权限？

【解决方案2】：

运行 Apache 的用户无权写入您的 /tmp/ 目录。

我建议的方法如下：

在非 root 用户下将 Apache 作为守护进程的代理运行。
将日志文件夹从 /tmp/ 更改为 /tmp 中的某个子文件夹，例如 /tmp/projectname
添加apache用户，写入那个文件夹的权限。
