[Bug]: ESModulesLinkingError (module has no exports) since v2

[Agritite]

System Info

System: Windows 11 22631 x64

Details

See the reproducible example repo;

on rspack@1.7.11 it succeeds, but on rspack@2.0.4 it fails with

ESModulesLinkingError: export 'default' (imported as 'dayjs') was not found in 'dayjs' (module has no exports)

Note: ignore the repo name; the main branch was for a previous bug

Reproduce link

https://github.com/Agritite/rspack-10456-repro/tree/no-exports

Reproduce Steps

1. pnpm run build
2. see error
3. downgrade rspack to 1.7.11 i.e.

pnpm remove @rspack/cli @rspack/core
pnpm add -D @rspack/cli@^1 @rspack/core@^1

4. pnpm run build
5. succeeds

Note: you can also change the target to node24.15 or electron41.6-renderer; both also makes rspack@2 succeed
i.e. only when target: "web" + rspack@2 = ESModulesLinkingError

Did some more testing and this now seems more like the result of a fix rather then a regression, because if I change target to "browserslist: chrome 146" then it succeeds. Could it be that rspack v1 didn't enforce "target: web" as strict as v2? I didn't find anything related in "migrate from v1 to v2" though.

Should be issue with config, the builtin:swc-loader hit all modules, and you haven't specify the isModule config, so swc transforms your source code into another format by default, you just need to add exclude /node_modules/ or specifiy isModule: 'unknown' for swc loader options
