angular - 错误 TS2307：找不到模块“@ng-bootstrap/ng-bootstrap”

问题描述

我在 Angular 5 项目中添加了 NGBootstrap。但过了一段时间它不起作用，我得到了错误。尝试通过升级 CLI 版本来解决问题，但问题仍未解决。请检查 package.json。

src/app/app.module.ts(5,27) 中的错误：错误 TS2307：找不到模块“@ng-bootstrap/ng-bootstrap”。src/app/find-product/searchtabcontent/search-by-family/search-by-family.component.ts(2,48): 错误 TS2307: 找不到模块'@ng-bootstrap/ng-bootstrap'

解决方案

如果您在删除 node_modules 后已经尝试重新npm install，问题仍然存在，并且您还仔细检查了“@ng-bootstrap”是否在您的 node_modules 目录下，我将按照以下步骤进行：

  • 我会尝试首先重新启动 IDE，Visual Studio Code 和其他人也会发生这种情况......

  • 你也可以试试这个（这适用于linux）：

    1. sudo npm install --save @ng-bootstrap/ng-bootstrap
    2. cd @ng-bootstrap
    3. sudo npm install

  • 确保，如果你有多个模块，只有 app.module 有 import like NgbModule.forRoot()，任何其他模块应该只NgbModule在 import []

希望能帮助到你 ：）
