python - 导入错误 : No module named pyodbc (Windows )

Question

Python 3.3，pip 已安装，PATH 为:

C:\Python33\Scripts 

我已经下载了 visual c++ 2010，我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，我得到以下信息:

Answer 1

我在使用 SQLAlchemy 的 Python 2.7.9 下遇到了这个问题，解决方案是在我的站点包文件夹中解压 pyodbc .egg 文件。 我必须注意，我没有自己编译它，我下载了二进制文件 (pyodbc-3.0.7.win32-py2.7.exe) 并使用 easy_install pyodbc-3.0.7.win32-py2 安装了它。 7.exe

P.S:可以找到较新的 .whl 类型安装程序 here ，您可以使用 pip install [.whl file] 安装它们。这也可能有助于您安装 pyodbc。

导航到当前 virtualenv 的 \Lib\site-packages 文件夹(如果您不使用 virtualenv，则导航到您的主 Python 安装文件夹下)。

将 pyodbc-3.0.7-py2.7-win32.egg 重命名为 pyodbc-3.0.7-py2.7-win32.zip。

解压缩 zip 文件并将内容直接放在 \Lib\site-packages 文件夹中。

在我这样做之后，pyodbc 模块被识别并且 SQLAlchemy 可以导入它。
