Firebase服务错误:端口5000未打开.无法启动功能模拟器 [英] Firebase serve error: Port 5000 is not open. Could not start functions emulator

问题描述

我正在尝试在本地提供Firebase功能，但是当我运行firebase serve或firebase emulators:start时，错误消息是:端口5000未打开，无法启动功能仿真器."

I'm trying to serve firebase functions locally, but when I run firebase serve or firebase emulators:start the error message is: "Port 5000 is not open, could not start functions emulator."

我使用的是Windows 10，因此我尝试更改端口号，检查端口是否被防火墙阻止，并且在防火墙中为端口5000-5010创建了新规则，但这些方法均不适用于我

I'm using Windows 10, so I've tried to change the port number, check if the port is blocked by Firewall and I create a new rule in Firewall to ports 5000-5010 but none of this approaches worked for me.

推荐答案

最近在官方github存储库中报告了一个类似的问题:

A similiar problem has recently been reported in the official github repo: https://github.com/firebase/firebase-tools/issues/1606.

这是由依赖项(节点端口查找器)中的错误引起的，如您在此处看到的. https://github.com/http-party/node-portfinder/pull/86

It is caused by a bug in a dependency (node portfinder), as you can see here. https://github.com/http-party/node-portfinder/pull/86

一个快速的编辑方法可能是使用旧版本的节点端口查找器(v 1.0.21).另外，您可以通过编辑node_modules/firebase-tools/lib/emulator/controller.js并将yield pf.getPortPromise({ port, stopPort: port })更改为yield pf.getPortPromise({ port, stopPort: port + 1 })来实现.

A quick fix to edit it might be to use the old version of node portfinder (v 1.0.21). Alternatively, you can do it by editing node_modules/firebase-tools/lib/emulator/controller.js and changing yield pf.getPortPromise({ port, stopPort: port }) to yield pf.getPortPromise({ port, stopPort: port + 1 }).

如Mladen Skrbic所建议，要找到firebase-tools文件夹，应运行npm root -g并在其中找到firebase-tools文件夹.

As suggested by Mladen Skrbic, in order to find the firebase-tools folder, you should run npm root -g and find the firebase-tools folder in there.

这应该可以解决问题！
