Virtualenv: brew python2에 대한 venv를 생성하는 Virtualenv 20.0.0b1 오류

@matthew-brett 확인이 필요합니다. 이 사실을 알려주셔서 감사합니다.

흠, 나는 이것을 재현할 수 없다 🤔 -vvv 출력을 게시할 수 있습니까?

어떻게 든 /usr/local/bin/python2 는 /usr/local/bin/python2.7 /usr/local/bin/python2 번역됩니다 ... /usr/local/bin/python2.7 가리키는 것은 무엇입니까?

그것은 제공합니다 :

$ ls -al /usr/local/bin/python2.7
lrwxr-xr-x  1 brettmz  admin  39 Nov 15 12:04 /usr/local/bin/python2.7 -> ../Cellar/python@2/2.7.17/bin/python2.7

/usr/local/bin/python2 인터프리터를 직접 시작하면 정상적으로 작동하지만 이전 virtualenv에서 작동한다는 사실에서 비롯된 것 같습니다.

시도해 볼 수 있다면 https://github.com/pypa/virtualenv/pull/1513에서 해결할 수 있을 것 같아요 🤔

공평하게 여기에서 올바른 테스트는 /usr/local/bin/python2.7 를 사용하여 먼저 파이썬을 만든 다음 /usr/local/bin/python2 ...를 사용하여 파이썬을 만드는 것이며 둘 다 작동해야 합니다.

나는 https://github.com/pypa/virtualenv/pull/1513 이 적어도 내 테스트에 따르면 이 문제를 해결했다고 믿습니다. 그렇지 않은 경우 언제든지 다시 보고해 주시면 문제를 다시 열 것입니다.

수정되지 않은 베타에서는 다음과 같이 작동합니다.

virtualenv --python=/usr/local/bin/python2.7 foo

둘 중 하나는 현재 discovery 브랜치에서 작동합니다.

빠른 답변 감사합니다.

시간을 내어 새 버전을 테스트해 주셔서 감사합니다.
