Linuxbrew Nodejs - 绑定到端口 80

Question

我想解决本期中描述的相同问题。

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

发生这种情况是因为文件夹名称是.linuxbrew，如果是，我该如何修复它？

Answer 1

发生这种情况是因为您试图在符号链接上运行它。尝试运行这个：

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