npm dependency resolution error with Symfony-provided package.json file

[mbtuckersimm]

My app is using Symfony 5.4 because we are still stuck on an ancient version of PHP (7.2.24, currently). We are using Symfony Flex. I ran

composer require symfony/webpack-encore-bundle

which resulted in webpack-encore-bundle v1.17.2 being installed.

Then, when I ran npm install to install the dependencies, I got this error in dependency resolution:

npm error code ERESOLVE
npm error ERESOLVE could not resolve
npm error
npm error While resolving: @symfony/webpack-encore@4.7.0
npm error Found: @symfony/stimulus-bridge@4.0.1

npm error
npm error Fix the upstream dependency conflict, or retry
npm error this command with --force or --legacy-peer-deps
npm error to accept an incorrect (and potentially broken) dependency resolution.

The package.json file that appears when I run the composer require command includes these two lines:

"@symfony/stimulus-bridge": "^4.0.0",
"@symfony/webpack-encore": "^4.0.0",

which are what's causing the problem, since webpack-encore v4.7.0 declares a dependency on stimulus-bridge ^3.0.0.

What's going on here? I didn't change the package.json at all. Is there something about my configuration that's resulting in Symfony providing a requirements file with conflicting dependencies? Is there some way to fix it?

Looks like symfony/recipes#1378 was wrong, by not respecting the peer dependency of webpack-encore.
