php – 文件系统不可写

File system Not writable
The directory /Applications/MAMP/tmp/php does not exist.
You may need to set the correct directory at the file system settings page or
change the current directory's permissions so that it is writable.

我检查(sites / default / files)的权限,它有755权限,我将其更改为777但没有任何反应,所以我将其返回.

我有(主页?管理?配置?媒体)的以下设置：

Public file system path
sites/default/files

Temporary directory
/Applications/MAMP/tmp/php

这是我得到的错误：
