Question

我有Xcode版本7.3.1节点版本v4.4.6和npm版本3.8.6

所以现在我的ios React Native应用程序正在构建，没有任何问题，但我正在尝试使用库：https://github.com/aksonov/react-native-router-flux/blob/master/docs/MIGRATION.md

需要React-native版本0.26.3

所以我检查了https://github.com/facebook/react-native/blob/0.26-stable/package.json，发现有一个稳定版本的React-native 0.26.3和React 15.0.2

所以我在package.json中更改了我对项目的依赖关系并删除了我的node_modules文件夹并重新安装。

  "dependencies": {
    "react": "15.0.2",
    "react-native": "0.26.3",
    "react-native-sound": "^0.8.3",
    "react-redux": "^4.4.5",
    "redux": "^3.5.2",
    "redux-thunk": "^2.1.0"
  }

然而，我的应用程序不再有效，我在启动时不断收到此错误。我该如何正确升级到React 15？

首先将您的react-native更新为较新版本，然后在项目根目录中运行此react-native upgrade。
