我是棱角分明的新手，我一直在努力了解更多有关angular2的信息。 我按照入门指南创建了angular2-quickstart项目。 但是当我运行命令npm start时，浏览器启动但是1秒后一切都失败了。 以下是我的npm错误日志文件的内容：

23 error Make sure you have the latest version of node.js and npm installed.
23 error If you do, this is most likely a problem with the angular2-quickstart package,
23 error not with npm itself.
23 error Tell the author that this fails on your system:

23 error You can get their info via:
23 error npm owner ls angular2-quickstart
23 error There is likely additional logging output above.

你能帮我弄清楚我做错了吗？

Change the Package.json Scripts Settings
"start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\",
to
"start": "concurrently \"npm run tsc:w\" \"npm run lite\" ",
angular 2 has moved from system js to webpack, find the sample app where you guys can get started with angular2 + webpack + Typescript https://github.com/IgnatiusAndrew/angular2-webpack-starter

尝试从终端运行package.json，看看输出是什么并修复它。如果问题出在tsc，则修复此问题应删除错误。
答案 3 :(得分：1)
我也有这个问题。似乎lite-server的依赖性是什么问题。
我更改了packages.json中的行：
"start": "concurrent \"npm run tsc:w\" \"node .\" "
这个解决方案可以帮助我进一步研究Angular2，但稍后会很好地解决lite-server的问题。

在我的情况下，我只是忘了跑

我通过改变来解决它：
＆＃34;同时＆＃34;：＆＃34; ^ 3.0.0＆＃34;，
到
＆＃34;同时＆＃34;：＆＃34; ^ 2.0.0＆＃34;，
package.json中的
答案 6 :(得分：0)
在Package.json脚本中，而不是从tsc部分删除start，我将其定义如下：
"tsc": "tsc",
"tsc:w": "tsc -w",
所以"scripts"现在看起来像这样：
"scripts": {
...
"tsc": "tsc",
"tsc:w": "tsc -w",
"start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\",
...
}
答案 7 :(得分：0)
解决了无法启动npm启动错误：
tsc && concurrently "tsc -w" "lite-server"
（以上所有尝试失败后）：在package.json中执行： “tsc”：“tsc”， “tsc：w”：“tsc -w”， “start”：“并发”tsc -w \“\”lite-server \“”，
