Question

我正在尝试构建一个Angular2应用程序，我想使用Grunt来部署它。出于某种原因，当我运行已部署的index.html时，我的代码不起作用。有问题的代码是角度网站的例子。我假设我要么缺少一个依赖项，要么没有正确部署soemthing。

当从终端运行“grunt”时，我收到错误：EBUSY：资源忙或锁定在“deploy”文件夹上。我怎么能让它起作用？任何帮助将不胜感激。

提前致谢，顺

我使用npm install使用以下 package.json 文件安装了依赖项：

你不应该使用Grunt，只需使用Angular CLI即可。它由有角度的团队维护并使用webpack捆绑器，因此不需要Grunt。

要编译您的应用，您需要运行 ng build ：

ng build --prod //this will also minify/uglify,...
