undefined不是对象(评估'RCTWebSockerManager.connect') - React Native

Question

我一直在关注如何将现有应用程序与native native集成的指南.http://facebook.github.io/react-native/docs/embedded-app-ios.html#content

根据我们的IOS人员的建议,我对IOS方面的一些自由行动.当我的视图加载时,我得到一个带有堆栈跟踪的红色错误屏幕:

(对不起,没有足够的声誉来发布图片.文字包括在下面.)

这是我的Podfile:

    pod 'FBSDKShareKit'
pod 'FBSDKCoreKit'
pod 'FBSDKLoginKit'
pod 'React'
pod 'React/RCTText'

("URL:"已更改为手动而非本地主机,但在浏览器中响应相同.)

当我跑:

(JS_DIR=`pwd`/ReactComponent; cd Pods/React; npm run start -- --root $JS_DIR)

一切都运行良好的日志yeilding:

    [22:32:15] <START> fs crawl
[22:32:16] <END>   fs crawl (744ms)
[22:32:16] <START> Building in-memory fs

[22:32:17] <END>   Building Haste Map (836ms)

一旦我在xcode ios-simulator中启动项目,我就得到了前面提到的堆栈跟踪.我可以包含我的目标c代码,如果它有用,但我省略了以防止混乱,因为它似乎是反应依赖的问题.

谢谢!任何帮助表示赞赏.

所以我想通了。如果您遇到此问题，请将我的 podfile 修复为有效。删除 Pods/ 目录，然后使用以下 podfile 再次运行 pod install。重新启动开发服务器也是一种好的措施。

pod 'FBSDKShareKit' pod 'FBSDKCoreKit' pod 'FBSDKLoginKit' pod 'React' pod 'React', :subspecs => [ 'RCTText', 'RCTImage', 'RCTNetwork', 'RCTWebSocket' ]
