角度找不到模块'./dropdown-basic'.ts(2307)

Question

我试图将Bootstrap DropDown添加到我的有角项目中。当我尝试将Bootstrap DropDown导入到app.module.ts文件时；通过添加以下代码行

import { NgbdDropdownBasic } from './dropdown-basic';

我遇到了错误。

找不到模块'./dropdown-basic'.ts(2307）

我试图通过删除node_modules并重新安装它们来解决此问题，但是问题仍然存在。请检查package.json。我可以手动安装该软件包吗？

Answer 1

从'./dropdown-basic'导入{NgbdDropdownBasic};

这是错误的导入，我认为您正在遵循文档，并且您认为这对下拉列表来说是重要的导入，但并非如此。

如果您已将其导入到模块中

从'@ ng-bootstrap / ng-bootstrap'导入{NgbModule};

那你很好。检查一下我如何使用下拉模块： https://stackblitz.com/edit/ngbd-dropdown-module
