Angular2使用vscode断点调试ts文件的方法

{
 "version": "0.2.0",
 "configurations": [ // 这个数组里包含了可以包含多个配置对象
  {
   "name": "ng serve", // 配置对象的名称，你可以选择其中一个配置运行调试
   "type": "chrome", 
   "request": "launch",
   "url": "http://localhost:4200/#",
   "webRoot": "${workspaceRoot}"
  },
  {
   "name": "ng test",
   "type": "chrome",
   "request": "launch",
   "url": "http://localhost:9876/debug.html",
   "webRoot": "${workspaceRoot}"
  },
  {
   "name": "ng e2e",
   "type": "node",
   "request": "launch",
   "program": "${workspaceRoot}/node_modules/protractor/bin/protractor",
   "protocol": "inspector",
   "args": ["${workspaceRoot}/protractor.conf.js"]
  }   
 ]
}

//1. 先卸载
npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli
//2. 全局安装
npm uninstall -g @angular/cli
npm cache clean
# if npm version is > 5 then use `npm cache verify` to avoid errors (or to avoid using --force)
npm install -g @angular/cli@latest
//3. 本地安装
npm install --save-dev @angular/cli@latest
