flutter doctor 执行报错

报错内容

Exception: Flutter failed to create a directory at "/Users/chaiguangpu/.config/flutter". The flutter tool cannot access the file or directory.

Please ensure that the SDK and/or project is installed in a location that has read/write permissions for the current user.

判断是文件权限问题

解决过程：

ls -la

chmod 777 .config（该名令执行结果：chmod: Unable to change file mode on .config: Operation not permitted）

sudo chmod 777 .config

再次执行

flutter doctor

解决
