Linuxbrew Nodejs - 绑定到端口80

Question

我想解决在this issue中描述的相同问题。

所以我想执行以下命令：

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

此产生的错误：

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 

这是否发生，因为文件夹名是.linuxbrew，如果是我怎么修复它？

Answer 1

它发生是因为你试图在符号链接上运行它。尝试运行此代替：

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