App won't build with yarn build

[undercontr]

Hello, I cloned the repo and installed the dependencies with yarn package. But when I want to build the next app with yarn build, below error appears,

PS D:\test\nextjs-starter-medusa> yarn build
next.config.js {}
   ▲ Next.js 14.0.4
   - Environments: .env.local

./src/app/[countryCode]/(checkout)/checkout/page.tsx:23:44
Type error: Parameter 'cart' implicitly has an 'any' type.

  25 |   if (cart?.items.length) {
  26 |     const enrichedItems = await enrichLineItems(cart?.items, cart?.region_id)
PS D:\test\nextjs-starter-medusa>

Does anybody bump this kind of build issues before on a clean cloned repo?

I am using

• Windows 11,
• Node v20.10.0,
• NPM 10.2.3,
• Yarn 3.6.1

To update here, it only works with yarn classic v1.22.19 not with yarn v3, even with nodeLinker, it does not calculate to exclude server components and sees them as a usual components. Same thing happens with pnpm v8 too. I think the issue here is yarn.lock file maybe does not supported by yarn v3?

@LXBUGR if you somehow accidentally removed the lock file, this is happens. i think this is mostly happens because of nexjs and typescript verison.
