在Mac OS X上安装libpq-dev [英] Install libpq-dev on Mac OS X

问题描述

我正在本地的Mac OS X上使用Postgresql后端运行Django。我已经使用pip安装了Django：

  sudo pip安装Django 
  

我已经安装Postgresql与其中一个二进制安装程序 here 。

但是当我尝试安装psycopg2我得到一个错误（粘贴在下面），它找不到pg_config。

从这个问题似乎我应该安装 libpq-dev 但我不知道如何。

我已经尝试使用MacPorts安装 libpqxx ，但没有做任何事情。

如何安装libpg-dev？还是还有其他的东西我失踪了？

解决方案

所以我结束了以下建议：

原来我没有安装 pg-config ，但是我不得不掏腰包去找一下。一旦我把路线中的一切都包括在内，一切都在游泳。以下是该链接的片段：

  PATH = $ PATH：/Library/PostgresPlus/8.3/bin/ sudo easy_install psycopg2 
  

我使用 pip 而不是 easy_install 和我的PostgreSQL安装目录略有不同，但这是要点。

I'm trying to run Django with a Postgresql backend on my local Mac OS X. I've installed Django using pip:

sudo pip install Django

I've installed Postgresql with one of the binary installers here.

But when I try to install psycopg2 I get an error (pasted below) that it can't find pg_config.

From this question it seems like I should install libpq-dev but I'm not sure how.

I've tried installing libpqxx with MacPorts, but that hasn't done anything.

How do I get libpg-dev installed? Or is there something else I'm missing?

解决方案

So I ended up following the advice here:

http://blog.jonypawks.net/2008/06/20/installing-psycopg2-on-os-x/

Turns out I did have pg-config installed, but I had to dig around to find it a bit. Once I included that in the path, everything worked swimmingly. Here's the snippet from that link:

PATH=$PATH:/Library/PostgresPlus/8.3/bin/ sudo easy_install psycopg2

I used pip instead of easy_install and my PostgreSQL installation directory was slightly different, but that's the gist.
