또한 gunicorn을 설치하는 동안 오류가 발생합니다. 이 예를 여기서 따랐 지만 아무것도 따르지 않았습니다. 내 가상 환경은 --no-site-packages플래그를 사용하여 생성되었습니다 . 우분투 13.10과 그리스 환경을 사용합니다. 그게 아닐까요?

답변

python-dev패키지처럼, C ++ 또는 C로 작성된 파이썬 확장의 컴파일이 필요합니다 psycopg2. 당신이 (예를 들어 우분투) 데비안 기반 배포를 실행하는 경우, 당신은 설치 python-dev실행

sudo apt install python-dev

또는

sudo apt install python3-dev

Python 버전에 따라 다릅니다 (예 🙂 sudo apt install python3.8-dev.

그런 다음 평소와 같이 환경 에 설치 psycopg2를 진행 하십시오 virtualenv.

답변

의 경우 Ubuntu 14.04Docker 이미지 python:3.4.3-slim에서이 조합이 저에게 효과적 이었습니다.

sudo apt-get update
sudo apt-get install -y build-essential
sudo apt-get install -y python3.4-dev
sudo apt-get install -y libpq-dev

pip3 install psycopg2

참고 build-essential패키지. 제 경우에는 매우 중요했습니다.

답변

제 경우에는 (python 2.7 및 python 3.4가 설치된 우분투 12.04)

sudo apt-get install python3-dev

충분하지 않았습니다. 트릭은 무엇입니까

sudo apt-get install python3.4-dev

답변

먼저 python-dev를 설치하십시오.

sudo apt-get install python-dev

그리고 적절하게 사용하려면 다음을 시도하십시오.

이것은 UTF-8로 설정되지 않은 터미널의 인코딩과 관련이 있습니다. 내 터미널은 다음과 같습니다.

$ echo $LANG
es_UY.UTF-8
$ python
Python 2.7.3 (default, Apr 20 2012, 22:39:59)
[GCC 4.6.3] on linux2

>>> s = '(\xef\xbd\xa1\xef\xbd\xa5\xcf\x89\xef\xbd\xa5\xef\xbd\xa1)\xef\xbe\x89'
>>> s1 = s.decode('utf-8')
>>> print s1
(｡･ω･｡)ﾉ
>>>

설정을 해제하면 동일한 오류가 발생합니다.

답변

데비안 : 

sudo apt-get install gcc

답변

나는 모든 해결책을 시도했지만 작동합니다.

pip install psycopg2-binary

lib를 설치 한 후 import psycopg2 python 파일에서 사용할 수 있으며 추가 db 연결 구성

답변

최신 Python 3.7의 경우 다음을 설치해야했습니다 python3.7-dev.

sudo apt-get install -y python3.7-dev
