Question

只是按照 facebook.github 上的说明创建-react-native-app首先得到:react-redux 5.0.6 requires a peer of react@^0.14.0 || react @^15.0.0-0 ....然后我卸载了 react-redux 现在得到这个......

here is package.json

启动打包器时出错

当我安装 react-navigation 包时，我发生了错误。我已经解决了我的问题

1. 删除node_modules、package-lock.json
2. 运行“yarn 安装”。
3. 运行“npm start”。
