create-react-app: babel-preset-react-app dependency error - Yarn 3

Describe the bug

When attempting to use create-react-app with yarn 3, running the scripts returns the following error

Error: [BABEL] src/index.tsx: babel-preset-react-app tried to access @babel/plugin-proposal-private-property-in-object, but it isn't declared in its dependencies; this makes the require call ambiguous and unsound.

One of your dependencies, babel-preset-react-app, is importing the “@babel/plugin-proposal-private-property-in-object” package without declaring it in its dependencies. This is currently working because “@babel/plugin-proposal-private-property-in-object” is already in your node_modules folder for unrelated reasons, but it may break at any time.

babel-preset-react-app is part of the create-react-app project, which is not maintained anymore. It is thus unlikely that this bug will ever be fixed. If you are starting a new project, you may consider using maintained alternatives such as Vite (https://vitejs.dev/) instead.

Add “@babel/plugin-proposal-private-property-in-object” to your devDependencies to work around this error. This will make this message go away.

How to resolve it

Hi. How is that CRA is not maintained anymore? You are writing in CRA issues list 😄 Isn’t this just some advertisement of the Vite project? 😄

#11751 seems like it will fix this.

Added this to my .yarnrc.yml file

nodeLinker: node-modules

yarnPath: .yarn/releases/yarn-3.1.1.cjs

Seems to have resolved it

In addition to what @llimos said, you also need to run yarn install afterwards to update your yarn.lock file with this change.

Is there a temporary fix for this, it seems I cannot use CRA with yarn workspaces currently

Thanks! #11751 is added to 5.0.1 milestone
