Answer 1

I got the following error when run the angular 4 project. 运行angular 4项目时出现以下错误。

module.js:538 throw err; module.js：538抛出err; ^ Error: Cannot find module '@angular-devkit/core' ^错误：找不到模块'@ angular-devkit / core'

To fix the error, just run.. 要解决该错误，请运行。

npm i -D @angular-devkit/core

also check in package.json folder, ^ symbol added in "@angular/cli":"^1.6.1", 还要检查package.json文件夹，在“ @ angular / cli”中添加^符号：“ ^ 1.6.1”，

    "devDependencies": {
    "@angular-devkit/core": "^0.4.3",
    "@angular/cli": "^1.6.1",
