ImportError：没有名为pyodbc的模块（Windows）

Question

Python 3.3，pip已安装且PATH为：

C:\Python33\Scripts 

我已下载visual c++ 2010，是否需要更改任何配置或将.bat文件添加到vc++的python 33包中？

当我尝试安装pyodbc时，我得到以下内容：

Answer 1

我在Python 2.7.9下使用SQLAlchemy遇到了这个问题，解决方法是在我的site-packages文件夹中解压缩pyodbc .egg文件。 我必须注意，我自己没有编译它，我下载了二进制文件（pyodbc-3.0.7.win32-py2.7.exe）并使用<html> <head> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script> </head> <body ng-app="defaultValueSelect"> <div ng-controller="ExampleController"> <form name="myForm"> <label for="mySelect">Make a choice:</label> <select name="mySelect" id="mySelect" ng-options="option.name for option in data.availableOptions track by option.id" ng-model="data.selectedOption"></select> </form> <hr> <tt>option = {{data.selectedOption}}</tt><br/> </div> </body> </html>安装了它

P.S：可以找到更新的.whl类型安装程序here，您可以使用easy_install pyodbc-3.0.7.win32-py2.7.exe安装它们。这也可能有助于你安装pyodbc。

导航到当前virtualenv的pip install [.whl file]文件夹（如果您未使用virtualenv，则导航到主Python安装文件夹下）。

将\Lib\site-packages重命名为pyodbc-3.0.7-py2.7-win32.egg。

解压缩zip文件并将内容直接放在pyodbc-3.0.7-py2.7-win32.zip文件夹中。

在我这样做之后，pyodbc模块被识别，SQLAlchemy可以导入它。
