无法在 macos-10.15.6 上使用 ruby-2.6.6 捆绑安装 puma 4.3.5 或 gem puma 尝试捆绑我的项目的依赖项，但 puma 4.3.5 出现错误。有人知道这个吗？

这是错误内容：

current directory: …我正在尝试ng-bootstrap在带有Angular 2的Reactive Form上使用Typeahead组件,在查看Typeahead文档中的示例代码后,我无法使其工作.
目前,我有类似的东西:
<input type="text" aria-describedby="cityValid" class="form-control" id="inputCity" [formControl]="userForm.controls.city" [ngbTypeahead]="search">
使用search与示例代码几乎相同的函数,但它使用以下堆栈跟踪失败
error_handler.js:53 TypeError: Cannot read property 'subscribe' of undefined

我究竟做错了什么？如果有一个关于如何在Reactive Forms上使用ng-bootstrap组件的一般指南会很棒,因为该示例基于基于模板的示例.
谢谢!
