我已经升级了react和react-native依赖项。当我试图在一个真实的设备上构建和运行我的原生react应用程序时，我在xcode中得到了以下堆栈跟踪，并且在启动后应用程序在白屏上冻结。

当我在android studio中运行相同的项目时，我得到了以下堆栈跟踪：

E/ReactNativeJS: JSON Parse error: Unexpected identifier "UIManager"
I/ReactNativeJS: 'Failed to print error: ', 'JSON Parse error: Unexpected identifier "SourceCode"'
W/unknown:React: Packager connection already open, nooping.
E/ReactNativeJS: Module AppRegistry is not a registered callable module.
E/ReactNativeJS: Requiring module "173", which threw an exception.
I/ReactNativeJS: 'Failed to print error: ', 'Requiring module "173", which threw an exception.'
I/ReactNativeJS: 'Failed to print error: ', 'JSON Parse error: Unexpected identifier "ExceptionsManager"'

Package.json

{
  "dependencies": {
    "react": "15.3.2",
    "react-dom": "15.3.2",
    "react-native": "^0.34.1",

我今晚遇到了这个。这对我来说是一个缓存问题。重新启动React Native Packager。

package.json无效。下面是来自json-validator的响应：

Error: Parse error on line 1: "dependencies": { "react": "1 --------------^ Expecting 'EOF', '}', ',', ']', got ':'

它必须看起来像这样：

{ "dependencies": { "react": "15.3.2", "react-dom": "15.3.2", "react-native": "^0.34.1", "react-native-animatable": "0.6.1", "react-native-collapsible": "0.7.0", "react-native-drawer": "2.2.6", "react-native-htmlview": "^0.5.0", "react-native-push-notification": "^2.1.1", "react-native-viewpager": "0.2.11", "react-redux": "4.4.5", "redux": "3.5.2", "redux-thunk": "2.1.0" } }

在与现有应用程序集成时，我也遇到了同样的问题。我解决了。我在package.json中的"react-native“版本代码与安卓应用的不同，我使用npm安装了相同的版本。
