Upgrade of "next" package does not seem to update "@next/swc" optional dependency

[raphaelsaunier]

What version of Bun is running?

1.0.25+a8ff7be64

What platform is your computer?

Darwin 23.3.0 x86_64 i386

What steps can reproduce the bug?

1. Create a next.js project with npx create-next-app@latest
2. Upgrade next version (e.g. from 14.0 -> 14.1, or from 14.1 to 14.1.1-canary.36) in package.json
3. Run bun install

What is the expected behavior?

Next.js and its @next/swc_{platform} optional (peer?) dependency should both be updated to the specified version.

What do you see instead?

Next.js is correctly updated but @next/swc isn't and triggers a warning when running bun run dev or bun run build.

 ⚠ Mismatching @next/swc version, detected: 14.0.1 while Next.js is on 14.1.1-canary.36. Please ensure these match

Additional information

Workaround: yarn install once to fetch/link the correct package and the warning disappears.

Also, running bun pm cache rm does not solve the issue.

I'm having the same error, on Windows 11, with Next.js 14.

Yup, I just upgraded to Bun v1.1.27 and I can confirm that the issue still persists.

In the example below, it occurs after upgrading from Next 14.2.3 to 14.2.9:

$ bun i
[0.07ms] ".env"
bun install v1.1.27 (267afa29)

+ next@14.2.9
