bun does not recognize peer dependency conflicts

[andreasvh-conceto]

What version of Bun is running?

1.0.29+a146856d1

What platform is your computer?

Darwin 23.2.0 arm64 arm

What steps can reproduce the bug?

1. checkout the repository [email protected]:andreasvh-conceto/bun-conflicting-peer-dependency.git
2. run bun install && rm -Rf node_modules && npm i
3. bun will not complain about dependency conflicts , npm does

What is the expected behavior?

bun will recognize the peer dependency conflicts like npm does with:

What do you see instead?

I get a successful response without any peer dependency conflict

rm -Rf node_modules && bun install                                                                                                                                                                                                                       ─╯
bun install v1.0.29 (a146856d)

Additional information

for our pipeline we use currently bun. But we figured out, that we have diverse dependency version conflicts, which only occur with npm. It looks like bun does not recognize them.

@Jarred-Sumner Is this fixed in v1.1?

Hi,

I'm on a Mac and facing the same issue. I have React v18, but a package has a peer dependency on React v16. It ignores the peer dependency.

We are facing the exact same issue. Can I ask if there is any hope to get it fixed? The only alternative solution for us is to switch to npm which we are really avoiding (❤️ bun) @dylan-conway

@dylan-conway , @Electroid and @Jarred-Sumner , Is there any plan or roadmap detailing when and what gets prioritized?
