Question

我已按照https://angular.io/guide/quickstart中的说明操作，并使用npm install命令创建了相应的快速入门文件和已安装的依赖项。之后，当我发出 npm start 命令时，我收到以下错误。

Answer 1

首先，我尝试在命令提示符下运行此命令：

concurrently "npm run tsc:w" "npm run lite"

那很有用。然后，在package.json文件中，我替换了这一行：

"start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" ",

有了这个：

"start": "concurrently \"npm run tsc:w\" \"npm run lite\" ",

此时，npm start正常工作。希望有所帮助。

Answer 2

根据他们的文档，angular2至少需要node 5.x.x

来自site：

通过在终端/控制台窗口中运行node -v和npm -v，验证您是否至少运行了node v5.x.x和npm 3.x.x.较旧的版本会产生错误。

看起来你正在运行node v0.10.25。尝试升级。

要升级，您可以使用nvm，以便在版本之间轻松切换。 GitHub上的nvm。

无法使用npm start启动应用程序
