Error build IOS release using React Native

Question

I have developed a full app using React Native and it is also working fine for Android but this is my first time doing in iOS and when I tried to build on iOS then the app builds successfully but when the app opens in the emulator then in Xcode it shows the following error

 2018-03-24 18:15:03.964 [error][tid:com.facebook.react.JavaScript] Native module cannot be null. 2018-03-24 18:15:03.966535+0530 VwWoocommerceApp[14134:150196] Native module cannot be null. 2018-03-24 18:15:03.969 [fatal][tid:com.facebook.react.ExceptionsManagerQueue] Unhandled JS Exception: Native module cannot be null. 2018-03-24 18:15:03.969554+0530 VwWoocommerceApp[14134:150193] Unhandled JS Exception: Native module cannot be null. 2018-03-24 18:15:03.970 [error][tid:com.facebook.react.JavaScript] Module AppRegistry is not a registered callable module (calling runApplication) 2018-03-24 18:15:03.971150+0530 VwWoocommerceApp[14134:150196] Module AppRegistry is not a registered callable module (calling runApplication) 2018-03-24 18:15:03.995465+0530 VwWoocommerceApp[14134:150193] *** Terminating app due to uncaught exception 'RCTFatalException: Unhandled JS Exception: Native module cannot be null.', reason: 'Unhandled JS Exception: Native module cannot be null., stack: t@68:276 <unknown>@610:127 d@2:755 <unknown>@609:654 d@2:755 <unknown>@307:1275 d@2:755 <unknown>@306:141 d@2:755 <unknown>@12:42 d@2:755 n@2:326 global code@612:8 ' *** First throw call stack: ( 0 CoreFoundation 0x00000001111cc12b __exceptionPreprocess + 171 1 libobjc.A.dylib 0x000000010fabef41 objc_exception_throw + 48 2 VwWoocommerceApp 0x000000010ec3e0e2 RCTFormatError + 0 3 VwWoocommerceApp 0x000000010ec3abb8 -[RCTExceptionsManager reportFatalException:stack:exceptionId:] + 507 4 CoreFoundation 0x000000011115036c __invoking___ + 140 5 CoreFoundation 0x0000000111150240 -[NSInvocation invoke] + 320 6 CoreFoundation 0x0000000111168c26 -[NSInvocation invokeWithTarget:] + 54 7 VwWoocommerceApp 0x000000010ec50fe9 -[RCTModuleMethod invokeWithBridge:module:arguments:] + 602 

Due to the above error the apps open and shows nothing.

I have searched a lot and I am new to IOS development so I didn't know how to solve the error.

If anyone knows please help.

删除库并使用npm添加库，然后将它们链接到Xcode中的项目
