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？我也尝试在系统配置js中添加'map'，但在访问@ angular / core时没有采用'.js'扩展名（即使defaultExtension：'js'存在于系统配置js中） .
请帮忙！！！

我很傻，错过了包含bootstrap 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（它寻找@ angular / packages not angular /
在系统配置js中使用映射为角度rc版本，如下所示
和
的package.json
