Note: This error originates from the build backend, and is likely not a problem with poetry but with fasttext (0.9.2) not supporting PEP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "fasttext (==0.9.2)"'.

 

poetry add fasttext 명령어를 시도하는 과정 내에서

위와 같이 pybind11 모듈과 관련한 오류가 발생하면서 설치에 실패하였습니다.

 

출력 부분 맨 끝에 적힌 pip wheel --no-cache-dir --use-pep517 "fasttext (==0.9.2)

문구를 시도해보았지만 마찬가지로 소용이 없었습니다.

 

 

해결 방법

pyproject.toml 파일을 연 뒤, 호환되는 fasttext 버전의 레포를 명시해주고,

다시 poetry install을 시도하였더니 해당 모듈을 정상적으로 이용할 수 있었습니다.

 

파일 내에서 fasttext의 의존성과 관련된 부분을 다음과 같이 추가해주시면 됩니다.

[tool.poetry.dependencies]
python = "^3.9"
fasttext = {git = "https://github.com/cfculhane/fastText.git"}
