我是 Angular 2 的新手。
我正在研究来自 Angular.io 的英雄应用程序。我正在修改它以使用 Angular 2。
我制作了一个按钮，单击该按钮会弹出窗口。现在我正在实现弹出窗口，然后我遇到了这个依赖项“--ng2-opd-popup。”
我将它添加到项目中，以便我可以使用弹出窗口，但这里事情变得很糟糕。
我执行了以下步骤来添加依赖项：
- 在 package.json "ng2-opd-popup": "^1.1.21",
- 运行命令 - npm install ng2-opd-popup --save 。
- 在 app.module.ts .import { PopupModule } from 'ng2-opd-popup' 中导入它；
- 运行服务器：
但它给出了错误：

如何添加依赖项 ng2-opd-popup 以便应用程序可以在项目中使用它？我花了几个小时在谷歌上搜索，现在我想不出任何办法。
npm install ng2-opd-popup 的输出
