【问题描述】：

我通过运行使用 facebook 指南安装了 expo

    npm install -g expo-cli
    npm install react-navigation
    expo start

但它仍然说

npm WARN @react-native-community/netinfo@2.0.10 requires a peer of react-native@>=0.57 <0.60 but none is installed. You must install peer dependencies yourself.
npm WARN react-google-maps@9.4.5 requires a peer of @types/googlemaps@^3.0.0 but none is installed. You must install peer dependencies yourself.

npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.9: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

我试图删除我的 node_modules 文件夹并在我的项目目录中重新运行 npm install

它仍然说 react-native not found，虽然正在运行

    react-native -v

在命令行中，显示

    react-native-cli: 2.0.1
    react-native: 0.60.3

【问题讨论】：

你的package.json是什么？

标签： react-native

【解决方案1】：

实际上你只安装 expo-cli 而不是 react native cli ，即使你的 package.json 有 react-native 它也不能从你的 cli 访问。所以你必须单独安装 react-native-cli 才能访问 react-native。

npm install –g react-native-cli
