Question

我正在尝试创建一个使用angularfire2作为firebase的应用。但我收到以下错误：

打字稿错误通用类型＆＃39; Observer＆＃39;需要2个类型的参数。 ... node_modules/@firebase/app-types/private.d.ts

将服务名称转换为要使用的工厂名称。 * / useAsService（app：FirebaseApp，serviceName：string）：string |空;

这是我的package.json文件....

npm install angularfire2@5.0.0-rc.6.0 --save

npm install firebase@4.12.1

通用类型＆＃39; Observer <v，e =“”>＆＃39;需要2个类型的参数。 @火力/应用类型/ private.d.ts
