为什么我在node_modules中有@ angular/core，但仍然出现这个错误？

我从网上下载angular.io一个例子项目，从这里 https://angular.io/generated/zips/cli-quickstart/cli-quickstart.zip 为什么我在node_modules中有@ angular/core，但仍然出现这个错误？

就跑在根文件夹故宫安装，如在本教程中

和somewhy，虽然我已经对应在node_modules和package.json中的角度包，我仍然得到这个：

您需要发布你的代码。没有人会观看该视频来帮助你。你的解决方案中包含哪些文件？ – peinearydevelopment

这工作在类似的情况：

卸载您计算机上的NodeJS。

如果与可下载的安装程序包安装 - （添加或删除程序>选择和的NodeJS点击卸载）

下载并安装6.10.3的NodeJS（https://nodejs.org/dist/v6.10.3/node-v6.10.3-x64.msi）

清理node_modules文件夹

rm -rf node_modules/

清理任何临时文件夹

运行这些命令

npm uninstall -g angular-cli 
npm cache clean 
npm install -g @angular/cli 
npm install
