Javascript Reactjs安装不当

当我在我的windows pc上执行

create react app

时，除了

node\u模块

之外，只安装依赖项，而不安装任何文件夹，即使使用

warn

，我也没有做得太多。请提前帮助和感谢。这就是我得到的

C:\Users\Arsh Deep\Desktop>create-react-app myapp2

这可能是由于网络速度缓慢或创建react应用程序版本

 1. Try to update the create-react-app version
 2. Or best uninstall create-react-app and use npx create-react-app to create react scaffold

这可能是由一些问题引起的

如果您以前没有遇到过此问题，我建议您检查连接，或者在可能的情况下更改连接以重试

其次，尝试更新您的工具

用npm试试这个，然后用CreateReact应用程序创建一个新项目

   npm rm -g create-react-app
   npm install -g create-react-app
   npx create-react-app my-app

---

您缺少

npx

，因此应该是

npx create react app myapp2

不起作用
