Vraag Fout bij het proberen Postgres voor python te installeren (psycopg2)


Ik heb geprobeerd psycopg2 in mijn omgeving te installeren, maar ik krijg de volgende foutmelding:

(venv)avlahop@apostolos-laptop:~/development/django/rhombus-dental$ sudo pip install psycopg2

Ik krijg ook fouten bij het installeren van gunicorn. ik volgde deze voorbeeld hier maar niets. Mijn virtuele omgeving is gemaakt met behulp van de --no-site-packagesvlag. Ik gebruik ubuntu 13.10 en de Griekse omgeving. Misschien is het dat?

antwoorden:


De python-dev pakket is vereist voor het compileren van Python-extensies geschreven in C of C ++, zoals psycopg2. Als u een Debian-gebaseerde distributie (bijvoorbeeld Ubuntu) gebruikt, kunt u deze installeren python-dev door rennen

apt-get install python-dev

of

apt-get install python3-dev

afhankelijk van je python-versie.

Daarna doorgaan met installeren psycopg2 in uw virtualenv omgeving zoals gebruikelijk.

Voor Ubuntu 14.04, van Docker-afbeelding python:3.4.3-slim deze combinatie werkte voor mij:

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

Notitie build-essential pakket. Het was cruciaal in mijn geval.

In mijn geval (ubuntu 12.04 met python 2.7 en python 3.4 geïnstalleerd)

sudo apt-get install python3-dev 

was niet genoeg. Wat was de truc?

sudo apt-get install python3.4-dev

Installeer allereerst python-dev

sudo apt-get install python-dev

En om te gebruiken, probeer dit:

Dit heeft te maken met het feit dat de codering van uw terminal niet op UTF-8 is ingesteld. Hier is mijn terminal:

$ 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
>>> 

Als ik uitschakel kreeg ik dezelfde fout die je kreeg:

$ unset LANG
$ python
