我从最新文档的源代码中设置了ckan。当用户尝试关注组织时，我的浏览器界面上会出现以下错误：
404 Not Found
The resource could not be found.
Incorrect group type
当我在virtualenv中使用“paster serve /etc/ckan/default/development.ini”命令运行网站时，我在关注组织时在我的网站上收到以下错误：
"Server Error
An internal server error occurred"
我在终端上得到以下追溯：

请帮忙。
答案 0 :(得分：3)
例外情况是由于文件权限而无法创建目录。在命令行上尝试相同的事情：
mkdir -p /tmp/default/sessions/container_file_lock/4
假设失败，那么你有两个选择：
cache_dir。答案 1 :(得分：0)
这是纯粹的目录权限
drwxr-xr-x. 3 root root 16 May 8 17:33 4
确保权限是这样的。
此外，请确保您对此目录具有正确的用户和组权限（递归）
/tmp/default/sessions/container_file_lock/4
