问题描述
我知道 Angular2 测试版刚刚发布，但我无法从他们的官方网站教程(https://angular.io/guide/quickstart).也许有人遇到过类似的问题并且知道该怎么做才能解决这个问题?当我尝试使用 npm start 命令启动应用程序时，我得到如下输出:
I know Angular2 beta has just been released but I can't reproduce the steps from their official site tutorial ( https://angular.io/guide/quickstart ). Maybe someone has had similar issues and knows what to do in order to fix the this? When I try to start the application with npm start command I get output like this:
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 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
I had: typescript 1.7.5 version node 0.12.2 version
也许有人可以帮助解决问题:)?

推荐答案
更改 package.json 中的 start 字段从
Change the start field in package.json from
"start": "tsc && concurrently "npm run tsc:w" "npm run lite" "
到
"start": "concurrently "npm run tsc:w" "npm run lite" "
