[bug] yarn install fails on minimal repo after paraglide init

[jldec]

Problem

yarn appears to have slightly different peer dependency resolution compared to npm or pnpm.

This results in a failure installing @inlang/paraglide-js in projects or environments (like codesandbox) where yarn is the default.

}

Expected behavior

paraglide-js should work in projects that use yarn.

Reproduction

Run the following in an empty directory:

yarn init -y
git init
npx @inlang/paraglide-js@latest init
yarn install

Great haha. This is an SDK issue (the position we are hiring)

[JoshuaHintze]

Just came here to say this. Saw the same thing. For now I guess I'll just manually add.

yarn version: 1.22.21

We should probably drop support for yarn below v3.

• sveltekit and other libs are dropping support
• yarn <3 is broken because it deviates from node module resolution
