我看到 ng2-bs3-modal 模块仍在尝试访问 @angular/core，我认为它应该指向 angular2/core？ 我还尝试在系统配置 js 中添加“地图”，但在访问 @angular/core 时它没有采用“.js”扩展名（即使系统配置 js 中存在 defaultExtension：“js”）。
请帮忙！！！

【参考方案1】：我太傻了，错过了包含引导 CSS
https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.6/css/bootstrap.css
并添加 ng2-bs3-modal 最新版本（它会寻找 @angular/ 包而不是 angular/
"ng2-bs3-modal": "^0.6.1"
在系统配置js中使用了angular rc版本的映射，如下所示
var map =
'app': 'app', // 'dist',
'@angular': 'node_modules/@angular',
'angular2': 'node_modules/@angular',
'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
'rxjs': 'node_modules/rxjs'
;
和
