Linuxbrew绑定到端口80

Question

我想解决本期中描述的同样的问题。

因此，我想执行以下命令：

$ sudo setcap cap_net_bind_service=+ep /home/username/.linuxbrew/bin/node 

这就产生了错误：

Failed to set capabilities on file `/home/username/.linuxbrew/bin/node' (Invalid argument)
The value of the capability argument is not permitted for a file. Or the file is not a regular (non-symlink) file

这是否是因为文件夹名为.linuxbrew而发生的?如果是，我如何修复它？

Answer 1

发生这种情况是因为你试图在一个符号链接上运行它。试着运行以下代码：

sudo setcap cap_net_bind_service=+ep $(readlink -f ~username/.linuxbrew/node)
