Peer dependency not met: doc@workspace:packages/docs doesn't provide @types/react

[samsnori]

I've just updated my Docusaurus to 3.8.1. and I'm now seeing this peer dependency issue:

 doc@workspace:packages/docs doesn't provide @types/react 

What's the correct way to solve this? Why is this listed as peer dependency?

Our init template has that dependency. It should be there. If you removed it, please add it.

Also we can't help much if you don't share a repro.

Thanks @slorber thanks for your reply!

Sorry for not providing a repro. I've got a yarn mono repo and one of the workspaces is a "install" of docusaurus. To install docusaurus I followed the installation process. Something like:

cd <repo>/packages
yarn dlx create-docusaurus@latest docs classic 

After installing like this, yarn will complain that a peer dependency hasn't been met. I can fix this by doing:

cd <repo>/packages/docs
yarn add @types/react

Though I wasn't sure if this is the common way to do this because I didn't find any info on this in the docs; probably because this depends on the packager manager.

Please run this outside of your monorepo, to show that it's not related to your monorepo setup.

Please share the exact yarn version you are using, and the full install log message

I suspect this kind of issue only happens on yarn v2+ and pnpm, see also related issue: #10668
