os.ip() throws error on linux without eth0

[jimmyliao11]

console.log(os.platform(), os.networkInterfaces());

linux {
  lo: [
    {
      address: '127.0.0.1',

      internal: true,
      cidr: '127.0.0.1/8'
    }
  ],

What's your question?

Thanks for reply. I want to get an IP, but this code will throw an error: TypeError: Cannot read property 'length' of undefined

https://github.com/SunilWang/node-os-utils/blob/master/lib/os.js#L101

    if (platform === 'linux') {
      for (i = 0; i < interfaces.eth0.length; i++) {
        if (os.networkInterfaces().eth0[i].family === 'IPv4') {
          ip = os.networkInterfaces().eth0[i].address
          break
        }
      }

      return ip
    }
