Peer dependency issue for mobx-react@6.3.1

[micnem]

Intended outcome:
npm install successfully with no peer dependency issues when on React 16.8.0 or higher, as stated in docs:

Actual outcome:
Getting error message:

npm ERR! ERESOLVE unable to resolve dependency tree

How to reproduce the issue:

Try installing mobx-react with React version 17.0.1.

For some reason I am unable to reproduce this issue in Sandbox / Expo but I am able to on this repo which was created with npx react-native@0.64.4 init and adding mobx@5.15.4 and mobx-react@6.3.1.

Versions

Listed in package.json of test repo.

Same here, would love to get a solution to this...

I think this was a documentation error. Mobx-react v6 won't support React v17. You should use mobx-react v7, or React v16. I opened a PR to fix the doc.

From #3832 it superficially seems mobx-react 6 does work correctly with React 17, just the peerDependencies is outdated (e.g. that version is older than React 17 itself). That could be changed by updating the package.json, but since we in principle don't release patches on 3 major version behind packages, I recommend to instead upgrade mobx-react to a newer version.

Closing as documentation has been updated per #3832. Thanks for the investigation @robhybrid!
