问题描述
我正在尝试使用
创建 React-native 应用程序环境create-react-native-app confusion
但它并没有创建所有文件。它只在混淆文件夹中创建 package.json 和 yarn.lock，缺少 App.js，我收到了下面提到的错误。

PS E:\Developer's Area\ReactNative-Projects>
这就是我设置应用程序的方式
yarn global add [email protected]
create-react-native-app confusion
yarn start
解决方法
[email protected] 不再支持，该版本是 4 年前发布的，最新版本是 3.5.3。您可以省略版本以获取最新版本 - yarn global add create-react-native-app 或使用 yarn create react-native-app 或 npx create-react-native-app。
此外，如果您想创建一个托管 expo 项目，我建议您安装 expo-cli - npm i -g expo-cli，然后运行 expo init。 full installation docs here。
