Answer 1

在path对象中：

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

在packages对象中：

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

Answer 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
