Django沒有名爲'psycopg2'的模塊

Question

嘿我試過找到解決我的問題的東西，但沒有任何幫助。我試圖在我的項目中安裝'psycopg2'來使用PostreSQL。

我試着用pip，easy_install等來安裝它。我使用PyCharm所以我嘗試安裝它我「安裝包窗口」，但我發現這樣的事情：

Collecting psycopg2 
    Using cached psycopg2-2.6.1.tar.gz 
    Complete output from command python setup.py egg_info: 
    running egg_info 
    creating pip-egg-info\psycopg2.egg-info

    warning: manifest_maker: standard file '-c' not found 

    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'. 

    ---------------------------------------- 

Command "python setup.py egg_info" failed with error code 1 in C:\Users\Bartek\AppData\Local\Temp\pycharm-packaging0.tmp\psycopg2\ 

我在Windows上工作，現在，你可以給我一些建議如何解決此問題？我坐在這2個多小時:(

安裝PostgreSQL的乾淨我試圖再次「PIP安裝psycopg2」我得到了後：
