如何在Python上使用“pip”安装psycopg2？
我使用的是virtualenv ，我需要安装“psycopg2”。
我做了以下工作：
pip install http://pypi.python.org/packages/source/p/psycopg2/psycopg2-2.4.tar.gz#md5=24f4368e2cfdc1a2b03282ddda814160
我有以下信息：

我的问题，我只需要做到这一点，让psycopg2工作？
python setup.py build_ext --pg-config /path/to/pg_config build ...
我发现这篇文章正在寻找针对这个问题的Linux解决方案。
“goshawk”这篇文章给了我解决方案：如果你在Ubuntu / Debian上，运行sudo apt-get install libpq-dev python-dev 。
更新
由于更多人发现这个答案很有用，并发布了他们自己的解决方案，下面列出了他们的解决方案：
于Debian / Ubuntu
Python 2
sudo apt install libpq-dev python-dev
Python 3
sudo apt install libpq-dev python3-dev
额外
如果以上都不能解决您的问题，请尝试
sudo apt install build-essential
要么
sudo apt install postgresql-server-dev-all
在CentOS上，你需要postgres开发包：
sudo yum install python-devel postgresql-devel
至少这是CentOS 6上的解决方案。
在使用Postgres.app版本9.3.2.0 RC2的Mac Mavericks中安装Postgres后，我需要使用以下代码：
sudo PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.3/bin pip install psycopg2
