Expo + vagrant，metro bundle 不起作用

Question

我创建了一个 VM 来处理 expo。我不能运行 Metro Bundle 在我主机的 19002 端口上的浏览器中。流浪文件：

# -*- mode: ruby -*-
# vi: set ft=ruby :

VAGRANTFILE_API_VERSION = "2"
REACT_NATIVE_PACKAGER_HOSTNAME = Socket.ip_address_list.find { |ai| ai.ipv4? && !ai.ipv4_loopback? }.ip_address

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
    config.vm.box = "geerlingguy/ubuntu1804"
    config.ssh.insert_key = false

    config.vm.provider :virtualbox do |v|
        v.name = "mobile-app"
        v.memory = 2048
        v.cpus = 1
        v.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]
        v.customize ["modifyvm", :id, "--ioapic", "on"]
    end

    config.vm.synced_folder "./", "/home/vagrant/workspace", type: 'nfs', mount_options: ['nolock,vers=3,udp,noatime']

    config.vm.hostname = "mobile-app"
    config.vm.network :private_network, ip: "192.168.33.40"
    config.vm.network "forwarded_port", guest: 3000, host: 3000
    config.vm.network "forwarded_port", guest: 19000, host: 19000
    config.vm.network "forwarded_port", guest: 19001, host: 19001
    config.vm.network "forwarded_port", guest: 19002, host: 19002
    config.vm.network "forwarded_port", guest: 19006, host: 19006

    config.vm.provision "shell", path: "install.sh"

    config.vm.provision "set_lan_ip", "type": "shell" do |installs|
    installs.inline = "
      echo 'export REACT_NATIVE_PACKAGER_HOSTNAME=#{REACT_NATIVE_PACKAGER_HOSTNAME}' >> /home/vagrant/.zshrc
    "
  end
end

当我运行npm start看到世博会开始的信息。我可以看到 url 和二维码图像：

Starting project at /home/vagrant/workspace/app
Expo DevTools is running at http://localhost:19002
Opening DevTools in the browser... (press shift-d to disable)
Starting Metro Bundler

当我运行localhost:19002和192.168.33.40:19002时，我看到：This site can’t be reached。但是当我启动 expo start:web 并打开时：192.168.33.40:19006 工作正常...当我在来宾上运行 curl localhost:19002 时，我可以看到 html，但是相同的 cmd在主机上获取：接收失败。（192.168.33.40同样报错）

我检查了端口：

node      1116         vagrant   21u  IPv4  21603      0t0  TCP 127.0.0.1:19002 (LISTEN)
node      1116         vagrant   22u  IPv6  21661      0t0  TCP *:19000 (LISTEN)
node      1160         vagrant   20u  IPv6  21720      0t0  TCP *:19001 (LISTEN)

网络活跃的地方：

node      1220         vagrant   22u  IPv4  22679      0t0  TCP *:19006 (LISTEN)

我觉得可能是端口的问题。 19002 映射到本地主机 (127.0.0.1)，但应允许在所有接口上使用。我可以在 expo 中设置它吗？

我的错误在哪里？

解决方法:

export EXPO_DEVTOOLS_LISTEN_ADDRESS=192.168.33.40

我使用了另一个参数，但这个是正确的...
