我一直在尝试通过运行 python setup.py install 来安装 pyodbc 3.0.7，但仍然有问题。目前我遇到了“错误：命令'cl.exe'失败：没有这样的文件或目录”墙。我在网上寻找的时间比我想承认的试图弄清楚发生了什么的时间要长。
我正在使用 64 位版本的 Python 3.4
我有 Microsoft Visual Studio 10.0。
我已确认 vcvarsall.bat 位于 Program Files (x86)\Microsoft Visual Studio 10.0\VC 中。
我正在运行 64 位，所以我添加了 amd64 文件夹并将 vcvars64.bat 放入 Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64
我确认 cl.exe 在 Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin 中
我重新启动计算机只是为了确保这不是问题所在。
但是当我尝试安装 pyodbc 时，我得到以下信息

从那里，作为最后的努力，我试图清理和建造，但遇到了同样的问题。

我一直使用 pip 所以这不是我熟悉的东西所以也许我做错了什么。任何帮助，我将永远感激不尽，因为我认为此时我已经用尽了所有资源。（或者 pyodbc 3.0.7 的预建副本也可以工作！）
