我是angular2和的新手material-design。我正在尝试将它们一起使用。

我cloned这个material2-app，它是基于angular2andmaterial2和 run的应用程序代码npm install。

当我运行此命令npm start启动服务器时。我得到了这个错误。任何线索？

我遇到了类似的问题。Angular 的新编译器 cli 似乎有问题。我通过添加以下解决了devDependencies它package.json

"@angular/compiler-cli": "^2.0.0"

再次执行后npm install，错误消失了。

你应该在 system.js 中添加 ng2material

作为

    var map = {
    'ng2-material': 'node_modules/ng2-material',
    };

    var packages = {
    'ng2-material': {defaultExtension: 'js'},
    };
