Jestem w Manjaro. Właśnie migrowałem z MySQL do PostgreSQL. Po wielu trudnościach instalacji PostgreSQL Uzyskaj błąd :( Wynik końcowy W przypadku instalacji PSYCOPG2:

pip install psycopg2

Wynik to:

Co to do zainstalowania?!

Wersja Django: 3 OS: Manjaro PostgreSQL z R (najnowsza wersja)

Najlepsza odpowiedź

Odpowiedź jest w błąd, który nam pokazałeś:

Możesz zainstalować pakiet binarny, instalując "Psycopg2 binary" z PYPI. Jeśli chcesz zainstalować PSYCOPG2 ze źródła, zainstaluj pakiety wymagane do budowy i spróbuj ponownie.

Więc spróbuj pip install psycopg2-binary lub upewnij się, że zainstalowałeś gcc przed instalacją ze źródła.

Należy pamiętać, że nawet po zainstalowaniu gcc prawdopodobnie będzie innymi błędami, w którym to przypadku będziesz musiał zainstalować te brakujące pakiety, dopóki nie ma już błędów. Na wspólnych dystrybucji Linuksa znajdziesz pakiet build-essential, który zawiera najczęstsze pakiety do budowy innych pakietów. Na Manjaro / Arch Linux jest to pakiet base-devel.
