postgresql - 在 windows 7 64 位 + python 3.4 上安装 psycopg2

Question

我已经阅读了几个相关链接。

1. 如果我尝试 python port for windows : 我使用的是 python 3.4，所以它失败了。

2. 对于下载存档+“setup.py install”或“pip install pyscopg2”，我收到以下错误。我安装了 visual studio 2012，我安装了 2010 版本来摆脱“找不到 vcvarsall.bat”

错误:

我尝试将 postregsql 安装路径的“lib”和“include”目录添加到我的路径中。事实上，缺少的符号似乎都在那里定义(libpq.obj/c/h)!启动了一个新的“cmd”，但结果相同。

Answer 1

我们最终通过 pip -> https://github.com/nwcell/psycopg2-windows 使用了这里的二进制文件通过 python 3.4

pip install git+https://github.com/nwcell/psycopg2-windows.git@win64-py34#egg=psycopg2

如本帖所述，http://www.lfd.uci.edu/~gohlke/pythonlibs/#psycopg也是一个很好的资源，但第一个解决方案解决了我的问题。
