Yarn Berry에서 ERR_LOADER_CHAIN_INCOMPLETE 오류

2022.10.29

Node.js의 버전을 18로 업그레이드하고 나서, Yarn Berry (Yarn v3)를 사용하는 프로젝트에서 다음과 같은 오류가 발생했다.

node:internal/errors:484
    ErrorCaptureStackTrace(err);
    ^

Error [ERR_LOADER_CHAIN_INCOMPLETE]: "file:///.../.pnp.loader.mjs 'resolve'" did not call the next hook in its chain and did not explicitly signal a short circuit. If this is intentional, include `shortCircuit: true` in the hook's return.

}

Node.js v18.12.0

해결법

yarn set version canary

Yarn 버전을 canary인 v4.0.0-rc.27로 업그레이드하여 문제를 해결했다.

Yarn 최신 버전에서 테스트 중인 Experimental ESM loader와 관련하여 문제가 발생한 듯하다.
