Cannot find package 'vitest'

[mbwestphal]

• @testing-library/jest-dom version: 6.6.3
• node version: v22.13.1
• jest (or vitest) version: 3.0.5
• npm (or yarn) version: [email protected]

Relevant code or config:

; .npmrc
hoist=false

What you did:

Tried running tests.

What happened:

Error: Cannot find package 'vitest' imported from /path/to/project/ui/node_modules/.pnpm/@[email protected]/node_modules/@testing-library/jest-dom/dist/vitest.mjs

Suggested solution:

vitest is declared in the devDependencies of @testing-library/jest-dom but it must be declared in the dependencies or peerDependencies because @testing-library/jest-dom/dist/vitest.mjs is importing vitests expect at test run time.
