ImportError：没有名为pyodbc的模块（Windows）

Question

Python 3.3 , pip is installed and PATH is:

C:\Python33\Scripts 

I have downloaded visual c++ 2010 , do I need to change any configuration or add the .bat file to python 33 package from vc++ ?

When I try to install pyodbc I get the following:

Answer 1

I had this problem under Python 2.7.9 using SQLAlchemy and the solution was to unpack the pyodbc .egg file in my site-packages folder. I must note that I didn't compile it myself, I downloaded the binary (pyodbc-3.0.7.win32-py2.7.exe) and I installed it using easy_install pyodbc-3.0.7.win32-py2.7.exe

PS: Newer .whl type installers can be found here , you can install them using pip install [.whl file] . That might also help you get pyodbc installed.

Navigate to the \\Lib\\site-packages folder for your current virtualenv (or under your main Python installation folder if you're not using a virtualenv).

Rename pyodbc-3.0.7-py2.7-win32.egg to pyodbc-3.0.7-py2.7-win32.zip .

Extract the zip file and place the contents directly in your \\Lib\\site-packages folder.

After I did this the pyodbc module go recognised and SQLAlchemy could import it.
