我在 Windows 操作系统上的默认反应应用程序不起作用

Question

我是 react-redux 和编码方面的新手，我正在努力学习。

所以我做了什么：

• 安装节点js
• 安装 npm i -g create-react-app
• 卸载 npm uninstall -g create-react-app
• 安装 npx create-react-app my-app-name
• cd my-react-app-name
• npm 启动

我的节点版本 node -v v14.16.0

mian-react-app@0.1.0 start
react-scripts start

‘Rudex\mian-react-app\node_modules.bin’ is not recognized as an internal or external command,
operable program or batch file.
