python - 在Mac OS X 10.9.5上安装Psycopg2

Question

我正在尝试在Mac-book上安装Psycopg2。我仍然遇到相同的错误。我在Stack Overflow上发现了很多相同的问题，但似乎没有答案。我认为这已经过时了。我正在使用:

Mac osx 10.9.5
Python 3.4.3
                 

我的错误代码是:

Running setup.py egg_info for package psycopg2 Error: pg_configexecutable not found.

Please add the directory containing pg_config to the PATH or specifythe 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'. Complete output fromcommand python setup.py egg_info: running egg_info

您似乎没有安装postgres，请检查如何在系统中安装postgresql，一种方法是brew install postgresql(如果您使用自制软件，建议使用)
或从postgresapp.com下载postgres应用程序，pg_config应该随postgres一起提供，而psycopg2试图找到它。
