There were package installation errors, make sure to read the log.

그런 다음 MacPorts를 사용하여 설치를 시도했지만 여전히 작동하지 않았습니다. 어떤 아이디어가 있나요?

Oskar-Niburskis-MacBook-Pro:~ oskarniburski$ sudo port install ruby19

이것이 나의 현재 경로입니다:

'which -a make'도, located -b '\make'도 마찬가지입니다. 첫 번째 명령에 대해 찾을 수 없는 명령과 후자에 대해 다음 명령을 찾습니다:illegal option --b
