我正在Ubuntu Server 14.04上部署django应用程序，我已经成功地在浏览器中找到了IP地址。但是，现在我收到一个标记为
的django调试错误[Errno 13]权限被拒绝：'。cache'
我不确定这意味着什么。应用程序被阻塞的路径是
/usr/lib/python3.4/os.py
这对我来说似乎很奇怪，因为我正在使用一个不在该目录下的虚拟环境来建立python版本和依赖项。
我意识到很多人都有同样的问题，但我还没有找到一个好的解决方案。我不是在寻找一个只允许某个目录的所有权限的解决方案;我想在应用此修复程序时保持良好的安全级别。谢谢你提前。

答案 0 :(得分：1)
这是你的错误：
File "var/www/html/scheduler.marist.edu/sched_app/sched_app/views.py", line 131, in
[Wed May 18 20:42:24.837054 2016] [:error] [pid 6078:tid 139663218018048] h = httplib2.Http(".cache")
这与django缓存无关，因为我（可能几乎所有读过此内容的人）都认为。这与您使用httplib2。
注释掉该部分代码，您就可以启动了。
<强>更新即可。我不是httplib2的专家，但我刚才读到的是“.cache”意味着httplib2将缓存它将检索的页面的目录。如果您没有传递该参数，它将不会缓存任何内容。如果要启用缓存，可能需要在此处使用安全但可写的路径。
