嘿，我试着找到解决问题的方法，但没有任何帮助。我正在尝试在我的项目中安装'psycopg2'来使用PostreSQL。
我尝试使用pip，easy_install等安装它。我正在使用PyCharm，所以我尝试安装它“安装包窗口”，但我得到这样的东西：
Collecting psycopg2
Using cached psycopg2-2.6.1.tar.gz
Complete output from command python setup.py egg_info:

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\
我现在在Windows上工作，你能给我一些建议如何解决这个问题？我坐了2个多小时:(
安装后清理PostgreSQL我再次尝试“pip install psycopg2”，我得到了：

安装Postgresql，在您的路径中添加C:\Program Files (x86)\PostgreSQL\9.4\bin\并再次尝试pip install psycopg2。
您似乎也需要下载Visual Studio。

我使用以下方法解决了我的问题：

这只是我的解决方案。视觉上，PostgreSQL对此没有帮助。
