Question

我目前正在处理使用expo创建应用程序时发布的默认存根代码（我已经创建了一些不同的屏幕并完成了一些样式）。但是，每当我在应用程序的目录中运行任何npm install命令时，该应用程序就会出现各种依赖性错误。

在npm install redux --save redux react-redux

之后输出终端

npm WARN package.json app@0.0.0 No repository field.

以下是ios模拟器中收到的输出：

Unable to resolve module `react-redux/lib/utils/storeShape` from `../app/node_modules/@expo/ex-navigation/src/ExNavigationProvider.js`: Module does not exist in the module map or in these directories:

      ../app/node_modules/react-redux/lib/utils
    ,   ../app/node_modules/react-redux/lib/utils

当我尝试删除并重新安装节点模块文件夹或重新安装npm时，我收到多个peerDependencies警告，然后是安装错误。我尝试在干净的项目中安装各种软件包，结果类似。在使用expo时，似乎其他人遇到了节点依赖性问题。

Answer 1

看起来你正在使用npm 2，因为create-react-native-app在某种程度上取决于npm 3+和Yarn的展平行为，所以不支持npm。

React Native也最好支持Node 6及更高版本，所以我也建议升级Node。

npm install break使用expo
