Question

我使用Python 3.4.3和PostgreSQL 9.4.4在Windows 7（64位）上安装psycopg，使用轮文件（来自http://www.lfd.uci.edu/~gohlke/pythonlibs/#psycopg）和命令：

pip install psycopg2-2.6.1-cp34-none-win_amd64.whl

我收到错误：

psycopg2-2.6.1-cp34-none-win_amd64.whl is not a supported wheel on this platform.

更新：我尝试使用easy_install命令：

easy_install psycopg2-2.6.1.win-amd64-py3.4-pg9.4.4-release.exe

Searching for psycopg2-2.6.1.win-amd64-py3.4-pg9.4.4-release.exe

Answer 1

您需要安装psycopg2‑2.6.1‑cp34‑none‑win32.whl。您的Windows可能是64位，但您的Python安装仍然是32位。您安装的软件包应该与您的Python安装相匹配，而不是Windows安装。

这是一个常见问题，因为http://python.org默认情况下会将您重定向到Python 32位，即使在使用Windows 64位甚至Chrome 64位浏览时也是如此。

Answer 2

试试这个：

C:\>python -m easy_install --upgrade setuptools
C:\>cd path\to\folder\psycopg
D:\path\>python -m pip install psycopg2-2.6.1-cp34-none-win_amd64.whl

无法在Windows 7上使用Python 3.4.3和PostgreSQL 9.4.4安装psycopg
