[英]Error: Can't resolve 'child_process' Angular-cli
I generated a new application using angular-cli and added few components. 我使用angular-cli生成了一个新的应用程序并添加了一些组件。 I haven't added any test cases.
我没有添加任何测试用例。 when I try to run/build the app, I get the following lengthy error message:
当我尝试运行/构建应用程序时,我收到以下冗长的错误消息:

I also found a similar question being asked here , but it is related to the test cases. 我在这里也发现了一个类似的问题,但它与测试用例有关。 Since I haven't written any test cases, that did not help me.
由于我没有编写任何测试用例,这对我没有帮助。
Got the culprit! 有罪魁祸首!
I was adding some events to one of the component and visual studio code imported event emitter from selenium instead of angular-core. 我正在从selenium而不是angular-core中添加一些事件给组件和visual studio代码导入的事件发射器。
deleted this 删除了这个
import { EventEmitter } from 'selenium-webdriver';
and updated this: 并更新了这个:
import { Component, OnInit, Input, EventEmitter } from '@angular/core';
Well, I don't have too much context here since you just posted errors, but this could be similar to Webpack and TypeScript: Cannot resolve module 'child_process' in node.d.ts . 好吧,我没有太多的上下文,因为你刚发布错误,但这可能类似于Webpack和TypeScript:无法解析node.d.ts中的模块'child_process' 。
Adding "target": "node"
to your webpack configs could resolve the issue. 在您的webpack配置中添加
"target": "node"
可以解决问题。
