无法在具有Python 3.4.3和PostgreSQL 9.4.4的Windows 7上安装psycopg [英] Can't install psycopg on Windows 7 with Python 3.4.3 and PostgreSQL 9.4.4

问题描述

我正在使用Wheel文件在Windows 7（64位）上使用Python 3.4.3和PostgreSQL 9.4.4安装psycopg（来自 http://www.lfd.uci.edu/~gohlke/pythonlibs/#psycopg ）和命令：

I'm installing psycopg on Windows 7 (64 bit) with Python 3.4.3 and PostgreSQL 9.4.4, using a wheel file (from http://www.lfd.uci.edu/~gohlke/pythonlibs/#psycopg) and the command:

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

我得到错误：

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

推荐答案

您需要安装 psycopg2‑2.6.1‑cp34‑none‑win32.whl 。 Windows可能是64位，但Python安装仍然是32位。安装的软件包应与Python安装匹配，而不与Windows安装匹配。

You need to install psycopg2‑2.6.1‑cp34‑none‑win32.whl. Your Windows might be 64-bit, but your Python installation is still 32-bit. The packages you install should match your Python installation, not your Windows installation.

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32位Python，即使在Windows 64位和Chrome 64位上浏览也是如此。

This is a common issue as http://python.org redirects you to Python 32-bit by default, even when browsing on Windows 64-bit and even with Chrome 64-bit.
