如何调试Ngrok没有通过节点模块启动

Question

我正在开发一个使用Ngrok进行开发的应用程序。从控制台运行Ngrok有效：

ngrok http 3011

示出了"；控制台UI"；指示隧道已打开，并给我要使用的url。

现在我正在尝试设置一些东西，这样开发人员就不需要复制粘贴URL等。但最基本的用法对我来说失败了：

// prepare-server.ts
import ngrok from 'ngrok'
import config from '../config'
(async () => {
try{
const nwhUrl = await ngrok.connect({ addr: config.serverPort })
console.log(nwhUrl)
} catch(e) {
console.error('problem with ngrok:', e)
}
})()

给我(当作为ts-node src/prepare-server.ts运行时(：

注意503服务不可用代码。如果CLI版本正常工作，情况如何？

有什么想法可以调试吗？我也尝试过这种不带选项的方法(await ngrok.connect()(，结果变化不大。这是一个绝对基本的例子(见文档(，所以我真的无法做更多的事情来简化代码，看起来像是关于Ngrok内部的东西。。。节点包为v4.0.1

PS这个问题可能是相关的或相同的。虽然我的问题发生在节点14.1.0上，但它不会发生在节点15.14.0上。

Answer 1

根据您提供的详细信息，这似乎是一个内部ngork错误，或者与某些特定节点版本不兼容。

尝试更新(有时甚至更旧！(版本的包和/或节点实际上并不太难，如果不能完全解决问题(就像在您的案例中发生的那样(，可能有助于阐明问题的性质。

如果更新没有解决问题，你能做的最好的事情就是在他们的Github回购上打开一个问题，因为这个问题在ngork内部工作中似乎已经足够深入，我预计不会有很多人能够提供帮助。
