【问题描述】：

我正在使用 firebase 为 firebase 项目实施 GoogleSign。我安装了这三个包：

    "@react-native-firebase/app": "^11.3.0",
    "@react-native-firebase/auth": "^11.3.0",
    "@react-native-google-signin/google-signin": "^6.0.0",

然后在我的 Login.js 文件中，我将它们导入为：

import auth from '@react-native-firebase/auth'
import  GoogleSignin  from '@react-native-google-signin/google-signin';

那么在function Login(props) 里面我已经

    GoogleSignin.configure(
        webClientId: 'MY_WEB_CLIENT_ID.apps.googleusercontent.com'
    );

但是一旦我运行我就会得到这个错误：

错误：需要模块 "node_modules/@react-native-google-signin/google-signin/src/GoogleSignin.js", 抛出异常：TypeError：null不是对象（评估 'RNGoogleSignin.SIGN_IN_CANCELLED')
