1. Application Shop-React-Native has not been registered. This is either due to a require() error during initialization or failure to call AppRegistry.registerComponent
解决办法:
造成这种错误有两种情况:
1. AppRegistry.registerComponent('项目名', () => 项目名); 与./ios/项目名/appDelegate.m中的RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation moduleName:@"项目名" initialProperties:nil launchOptions:launchOptions]; 不同
在Android项目中可能是./android/app/src/main/java/com/项目名/MainActivity.java中的mReactRootView.startReactApplication(mReactInstanceManager, "项目名", null); 没有保持一致,修改方法:编辑成相同的参数即可。
2. 有可能你同时在运行一个以上的程序。如果你的react-native在运行程序A而你打开了程序B,也会出现相同的问题。解决方法:关闭其它React Native程序, 只运行一个。
