我知道Angular2测试版刚刚发布，但我无法从其官方网站教程（https://angular.io/guide/quickstart）中复制步骤。也许有人遇到过类似的问题，并且知道该怎么做才能解决此问题？当我尝试使用npm start命令启动应用程序时，我得到如下输出：
0 info it worked if it ends with ok
1 verbose cli [ 'node', '/usr/local/bin/npm', 'start' ]
2 info using npm@2.7.4

18 error Failed at the angular2-quickstart@1.0.0 start script 'concurrent "npm run tsc:w" "npm run lite" '.
18 error This is most likely a problem with the angular2-quickstart package,
18 error not with npm itself.
18 error Tell the author that this fails on your system:
18 error concurrent "npm run tsc:w" "npm run lite"
18 error You can get their info via:
18 error npm owner ls angular2-quickstart
18 error There is likely additional logging output above.
19 verbose exit [ 1, true ]我有：打字稿1.7.5版本节点0.12.2版本
也许有人可以帮助解决问题:)？

app/它的内部还是外部？
首先，你的文件boot.js必须是打字稿文件重命名它作为boot.ts。我没有看到其他似乎有问题的地方……正如the_critic所说，您能否给我们您的项目结构。

它是boot.ts。我在stackoverflow上错误地输入了“ js”，抱歉。索引html位于根目录，例如package.json。它不在app /目录中。
