ImportError: nie można zaimportować nazwy md5

Naprawdę nie wiem, co się tutaj dzieje, muszę wdrożyć aplikację kolby na elastycznej łodydze fasoli, ale jakoś zmieniłem ścieżkę i nie mogę już uruchomić Python application.py

Też już zrobiłem:

LDFLAGS:  -L/usr/local/opt/openssl/lib
CPPFLAGS: -I/usr/local/opt/openssl/include

Nadal pojawia się ten błąd:

    from hashlib import md5, sha1, sha256
ImportError: cannot import name md5

Kiedy zrobię [brew link --force openssl], przejdę poniżej:

Używam macOS, napraw to brew unlink openssl && brew reinstall python@2

Osobiście używam i polecam pyenv do zarządzania wersjami Pythona. Na początku nie byłem pewien, jak to naprawić, i próbowałem ponownie zainstalować, używając brewsugestii tutaj . Jednak potem przypomniałem sobie, że pyenvinstalowałem i dzięki temu mogłem naprawić błąd.

pyenv install -f 2.7.15

Ta -fopcja wymusza instalację tej wersji, nawet jeśli już istnieje w systemie. Musisz użyć 2.7.16dowolnej wersji.

The python-build że pyenvzastosowania użyje opensslbibliotekę brew, jeśli jest ona dostępna.
