问题描述

我已经通过创建一个角度项目

I have create an angular project via

ng new project_name --style=scss

，然后尝试通过

ng serve

但出现错误

删除并重新安装了 node_modules ，但徒劳无功.

removed and reinstalled the node_modules but all in vain.

每次收到此错误时，请指导该怎么做！！！

Every time getting this error, please guide what to do!!!

为什么我不能在Office PC的 localhost (运行在192.168.XX:4200上)上运行 Angular 应用程序，但是可以在<在我家里的代码>本地主机

Why I am not able to run Angular application on localhost (running on 192.168.X.X:4200) in my office pc but the same project I can run on localhost at my home

更新2

在hosts文件中，我有这个.可以吗?

in hosts file, I have this. Is it OK?

127.0.0.1本地主机

127.0.0.1 localhost

:: 1本地主机

更新3

我很确定，这只是系统配置问题，因此它阻止了localhost并允许192.168.X.X，但不知道问题出在哪里.

I am quite sure, it is only the system config issue that's why it is blocking localhost and allowing 192.168.X.X but don't know where the problem lies.

推荐答案

我正在使用 Opera 浏览器进行测试，这是我的默认浏览器，并尝试访问 localhost:4200 ，但每次连接被拒绝时，我都会在 Chrome 上对其进行测试，它运行平稳.

I was using Opera browser for testing and it was my default browser and trying to access localhost:4200 but every time connection refused then I test this on Chrome, it ran smoothly.

我检查了两个浏览器的代理设置，并且没有启用代理.最后，我在 Opera 中重置设置和数据，并解决了问题.

I checked proxy setting for both the browsers and there was no proxy enabled. Finally I reset settings and data in Opera and problem resolved.

还是，问题在那里！！！是什么阻碍了 localhost ...

Still, question is there!!! What was that hindering localhost ...
