为Anaconda Python安装psycopg2 [英] Install psycopg2 for Anaconda Python

问题描述

我有Anaconda Python 3.4，但是每当我运行旧代码时，我都会通过键入"source activate python2"切换到Anaconda Python 2.7.我的问题是我为Anaconda Python 3.4安装了psycopg2，但没有为Anaconda Python 2.7安装.当我在Python 2.7上运行pip install psycopg2时，出现以下消息:

I have Anaconda Python 3.4, however whenever I run older code I switch to Anaconda Python 2.7 by typing "source activate python2". My issue is that I have psycopg2 installed for Anaconda Python 3.4, but not for Anaconda Python 2.7. When I run pip install psycopg2 (on Python 2.7) I get the following message:

Error: pg_config executable not found.
Please add the directory containing pg_config to the PATH
or specify the full executable path with the option:
    python setup.py build_ext --pg-config /path/to/pg_config build ...
or with the pg_config option in 'setup.cfg'.

我刚开始编程，需要以下方面的帮助:

I am fairly new to programming and need help in:

1. Obtaining directory containing pg_config
2. Finding the path to Anaconda Python 2.7 
3. Adding pg_config to the PATH.

完成这些步骤后，我应该可以进行pip install Install psycopg2

After I complete these steps I should be able to pip install Install psycopg2

推荐答案

您需要PostgreSQL的开发系统软件包，其中包含编译psycopg2扩展所需的头文件.对于我的CentOS 64位，要安装的命令是:

You need development system package for PostgreSQL which contains header files required to compile psycopg2 extension. For my CentOS 64 bit the command to install is:

yum install postgresql-devel.x86_64

但这取决于操作系统-对于Ubuntu，将是 apt-get install ... -软件包名称在发行版之间略有不同.
完成此步骤后，步骤2和3应该就不需要了.

but it depends on the OS - for Ubuntu that would be apt-get install ... - the name of the package varies slightly between distros.
Steps 2 and 3 should be unnecessary after you do this.

对于Mac OS来说，就是这样:

For Mac OS that would be just:

brew install postgresql
