I got this trouble when I try to install react JS with my npm.

this is the massage:

Unknown command: "create-react-app"
To see a list of supported npm commands, run:
  npm help

What should I do?

CodePudding user response：

Use npx create-react-app appname

React docs https://reactjs.org/docs/create-a-new-react-app.html

create-react-app is obsolete you must be using old docs or tutorials GoodLuck

CodePudding user response：

When you create react app use npx not npm.

npx create-react-app my-app
