CondaValueError: pip returned an error

원래는 이 명령을 통해 jekyll이 내장하고 있는 서버를 동작시키고 이를 로컬 PC(localhost:4000)에서 확인 가능한데, 에러

처리

프로젝트 폴더 environment.yml 에서 pip 밑에

• libcxx=4.0.1
• libcxxabi=4.0.1
• libgfortran=3.0.1

를 아래로 수정

• libcxx==4.0.1
• libcxxabi==4.0.1
• libgfortran==3.0.1

Error 2

위 내용대로 수정 후 업데이트

$ conda env update -f environment.yml

Could not find a version that satisfies the requirement libcxx==4.0.1 (from -r /Volumes/data_mb2/project/Server/condaenv.m4ug0hfc.requirements.txt (line 7)) (from versions: )
No matching distribution found for libcxx==4.0.1 (from -r /Volumes/data_mb2/project/Server/condaenv.m4ug0hfc.requirements.txt (line 7))
