Module '"util"' has no default export.

[fubhy]

Describe the bug

When enabling lib checks in a consuming application or library that uses vitest, but doesn't allow synthetic default imports you'll currently run into this error:

@vitest/utils/dist/index.d.ts(5,8): error TS1192: Module '"util"' has no default export

Reproduction

I think the issue is obvious but let me know if you think otherwise and I'm happy to produce a reproduction repo.

I'm experiencing this as well.

Workaround for now until that change gets released - exclude the test files from type checking:

tsconfig.json

{
  "//": "gets rid of the error:  'React' refers to a UMD global, but the current file is a module. Consider adding an import instead.'",
  "compilerOptions": {
    "jsx": "react-jsx"
  },
  "include": ["src/**/*"],
  "exclude": ["src/**/*.test.tsx", "src/**/*.test.ts"]
}
