React Native 项目

我在创建新的 React Native 项目时遇到问题，当我运行

react-native init AwesomeApp

我得到的只是（package.json 和 yarn-error.log），命令中没有 iOS 或 Android 文件夹

This will walk you through creating a new React Native project in /Users/man/AwesomeApp
Using yarn v1.16.0

Command `yarn add react-native --exact` failed.

我的堆栈是：

  • 节点：v12.5.0
  • npm： 6.10.0
  • 纱线：1.16.0
  • react-native-cli: 2.0.1
  • react-native：n/a – 不在 React Native 项目目录中

答案1

package.json您的主文件夹中有一个。这package.json似乎是无效的。

我建议您将其删除，因为它很可能不应该存在。

无论出于什么原因，Yarn 也会查看父package.json文件。

（另外建议您不要安装，react-native而是使用npx。）

答案2

npm install -g react-native-cli npm install

此命令将安装你的 iOS 和 Android 文件或节点模块
