我在 Angular 5 中有一个项目，我正在尝试使用 Google gapi.auth2 库实现登录。我被这个错误困住了：
ERROR in ./src/app/signin.service.ts
Module not found: Error: Can't resolve 'gapi.auth2' in 'C:\Users\Javier\workspace\angular-tour-of-heroes\src\app'
该错误似乎与我在服务中导入库的方式有关。
我的实现包括"@types/gapi.auth2": "0.0.47",通过添加到 package.json 文件npm install --save @types/gapi.auth2。添加import gapi.auth2到signin.service.ts，这是我试图从中调用gapi的Angular服务。
