在使用React Native过程中会遇到许多问题导致iOS端编译失败，一下是一个测试成功的配置：
{
"name": "NavigationDemo",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node node_modules/react-native/local-cli/cli.js start",
"test": "jest"
},
"dependencies": {
"react": "16.0.0-alpha.6",
"react-native": "0.44.3"
},
"devDependencies": {
"babel-jest": "20.0.3",
"babel-preset-react-native": "2.1.0",
"jest": "20.0.4",
"react-test-renderer": "16.0.0-alpha.6"
},
"jest": {
"preset": "react-native"
}
}
在修改完package.json后记得把node-moudles文件夹删除，并在命令行中运行：
npm install以此重新加载相关依赖包。
