我正在尝试在我的Angular 5项目中集成angularfire2和Firebase，但是它提示出现“firebase”命名空间错误。
package.json

}
我尝试了以下解决方案，但它们都没有解决我的问题。
- 在app.module.ts中使用'import * as firebase from'firebase';
- 在tsconfig.json中添加"types": ["firebase"];
- 使用'npm install --save @types/firebase'安装@types/firebase；
在这些步骤之后，我使用'typings install firebase --save'安装了firebase typings，并在tsconfig.json中添加了'"files": ["typings/index.d.ts"]'。它从控制台中删除了所有命名空间的错误，但是当我在浏览器中检查localhost:4200时，没有显示任何视图。通过检查元素，我可以看到没有在中呈现任何视图。
