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

[Mezzle]

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.

Did you try recovering your dependencies?

Thanks @Mezzle for reporting, we likely need to add @babel/plugin-proposal-private-property-in-object in the babel-preset-react-app package as a dependency in package.json

#11751 seems like it will fix this.

+1

[raix]

Thanks! #11751 is added to 5.0.1 milestone

[kevingilbert100]

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

[llimos]

Add to your .yarnrc.yml:

packageExtensions:
  babel-preset-react-app@*:
    dependencies:
      "@babel/plugin-proposal-private-property-in-object": "*"

[quisido]

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

[WegDamit]

why not just "yarn add @babel/plugin-proposal-private-property-in-object" ?

[quisido]

why not just "yarn add @babel/plugin-proposal-private-property-in-object" ?

Because that doesn't resolve the warning. That adds it to your package.json, which - as the error states - makes the import ambiguous and unsound.

Added this to my .yarnrc.yml file

nodeLinker: node-modules

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

Seems to have resolved it

[trohr]

This issue seems to be solved for us after upgrading create-react-app to 5.0.1 (and yarn to 3.3.1).

We have previously used solution provided by Ilimos (https://github.com/facebook/create-react-app/issues/11793#issuecomment-998230832). Now yarn start & yarn build works for us with that workaround removed from .yarnrc.yml.

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.

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