我遇到了这个错误,有人可以帮助我吗？我刚升级到Angular2.4.3

$ ng serve                                                                                                                                                                              [19:46:01]

main.ts

app.module.ts

修改tsconfig.app.json或tsconfig.json使用无效值时会发生这种情况.
