无法在具有Python 3.4.3和PostgreSQL 9.4.4的Windows 7上安装psycopg

Question

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

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

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 。 Windows可能是64位，但Python安装仍然是32位。 您安装的软件包应与Python安装匹配，而不与Windows安装匹配。

这是一个常见问题，因为即使在Windows 64位和Chrome 64位上进行浏览， http： //python.org也会默认将您重定向到32位Python。

Answer 2

尝试这个：

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
