React native React本机FBSDK登录不'；不要回复电子邮件

我正在尝试使用默认的已解决

---

嘿，你查过不同的facebook账户了吗？就像有些帐户没有通过电子邮件注册一样，我已经尝试使用我创建的2个帐户，使用2个不同的电子邮件。。。但结果是一样的。问题是，当我在facebook webview/native view中检查权限时，应用程序只请求public_配置文件，而不请求Email。您也可以在捕获条件下尝试public配置文件。然后用另一个帐户检查我，facebook现有的活跃帐户，它有email。没有什么改变了我们。太好了，很高兴你这么做了。我一直在努力解决这个问题很长时间了，你的答案终于解决了！谢谢！
