Question

我已经安装了Angular2 Material Design，并且这些库位于目录

中

node_modules/angular2-material

当我尝试从angular2-material导入任何组件时，我得到（在浏览器上）以下错误

zone.js:101 GET http://localhost:4200/vendor/@angular2-material/toolbar/toolbar.js 404 (Not Found)scheduleTask @ zone.js:101ZoneDelegate.scheduleTask @ zone.js:336Zone.scheduleMacroTask @ zone.js:273(anonymous function) @ zone.js:122send @ VM3502:3fetchTextFromURL @ system.src.js:1154(anonymous function) @ system.src.js:1735ZoneAwarePromise @ zone.js:584(anonymous function) @ system.src.js:1734(anonymous function) @ system.src.js:2759(anonymous function) @ system.src.js:3333(anonymous function) @ system.src.js:3600(anonymous function) @ system.src.js:3985(anonymous function) @ system.src.js:4448(anonymous function) @ system.src.js:4700(anonymous function) @ system.src.js:406ZoneDelegate.invoke @ zone.js:323Zone.run @ zone.js:216(anonymous function) @ zone.js:571ZoneDelegate.invokeTask @ zone.js:356Zone.runTask @ zone.js:256drainMicroTaskQueue @ zone.js:474ZoneTask.invoke @ zone.js:426

我有以下system-config.ts

const map: any = {

如果有人能指出我的错误，我将不胜感激。提前致谢

问题很简单。我没有更新angular-cli-build.js，因此@angular2-material目录中没有dist。
