【问题讨论】：

你有错误的url，因此404结果代码。

谢谢你的回答，但在哪里？？

从 'ng2-bootstrap' 导入 ModalDirective ;这是我在 schedule-list.component.js 中的导入

那么您认为这段代码在做什么？或者 import 语句中的“ng2-bootstrap”是什么？

在你的路径中：'moment': 'node_modules/moment/moment.js', 'ng2-bootstrap': 'node_modules/ng2-bootstrap/ng2-bootstrap.js',

【参考方案1】：

在你的路径对象中：

'moment':  main: 'moment.js', defaultExtension: 'js' ,
'ng2-bootstrap':  main: 'ng2-bootstrap.js', defaultExtension: 'js' 

在你的包对象中：

'moment':  main: 'moment.js', defaultExtension: 'js' ,
'ng2-bootstrap':  main: 'ng2-bootstrap.js', defaultExtension: 'js' ,

【讨论】：

谢谢你..我做了你上面提到的但没有用

看上面

尝试 'ng2-bootstrap': 'node_modules/ng2-bootstrap/ng2-bootstrap.js' 没有捆绑包

【参考方案2】：

ng-2 bootstrap：此包已弃用，已重命名为ngx-bootstrap。

尝试使用 npm 安装 ngx-bootstrap。

npm i ngx-bootstrap --save
