我尝试将权限添加到 .cipd 文件夹，但不起作用，我还对所有文件夹从“.cache”一直到“内容”进行 chmod 777

有人可以帮我吗？

Answer 1

这可能会解决权限被拒绝错误（运行不带前导

$

的命令）：

$ sudo chown -R namvp. /home/namvp/.cache
$ find /home/namvp/.cache -depth -type d | xargs -d '\n' chmod 755
$ find /home/namvp/.cache -depth -type f | xargs -d '\n' chmod 644

第一个命令 (

chown

) 递归地更改所有文件和目录的所有者和组。

接下来的两个命令（

find ... chmod ...

）递归地设置文件目录和文件的权限位（读-写-执行）。
