When I try to install react-codemirror2 it gave an error and doesn't install in my app (my react version is @17.0.2) Why it doesn't install?

Error list in below

  • Looks like you've React 17 installed and `react-codemirror2` has a peer dependency on React 16 (*and maybe some of React 15*), i.e. `"react": ">=15.5 <=17.x"`. Did you try any of the suggestions from the error message? There's ***at least*** one [open issue](https://github.com/scniro/react-codemirror2/issues/271) regarding React 17 compatibility. – Drew Reese Jan 29 '22 at 08:15
  • No actually, do I have to install react@16? – Mahdi Heydari Jan 29 '22 at 08:19
  • Rolling back to React 16 may be the cleanest path forward. – Drew Reese Jan 29 '22 at 08:19

If anyone else has the same problem like me He/she can just install "react-codemirror2-react-17" instead "react-codemirror2" It worked for me.

I faced a similar error message. Try using npm install react-codemirror2 --legacy-peer-deps

After writing:

"engines": {
    "node": "14.x"
  }

in package.json, react-codemirror2 worked correctly

use " npm install react-codemirror2 --force" The only option that worked for me. You should try.
