首次使用“create-react-app my-app”创建 React 应用

Question

我第一次尝试在我的本地机器上创建一个 React 应用程序。我已经使用“npm i -g create-react-app”在全局范围内成功安装了“create-react-app”安装后，当我尝试使用“create-react-app”创建一个反应应用程序时，它会创建应用程序的文件夹里面只有两个文件，分别是the items within the created folder 但是终端显示这个错误：

Error: Cannot find module 'cra-template/package.json'

  ]
}

Aborting installation.

Done.

我该怎么办？

Answer 1

我不知道您提到的创建新 React 应用程序的方法。你为什么不试试标准的方法？

您需要在您的机器上安装 Node >= 10.16 和 npm >= 5.6。要创建项目，请运行：

npx create-react-app my-app
cd my-app
npm start
