我一直在尝试通过运行python setup.py install来安装pyodbc 3.0.7但是仍然有问题。目前我已经点击“错误：命令'cl.exe'失败：没有这样的文件或目录”墙。我在网上看的时间比我想承认试图弄清楚发生了什么更长。
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
中我确认cl.exe位于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不是问题所在。
但是当我尝试安装pyodbc时，我得到以下内容

从那里开始，作为最后的努力，我试图清理和构建，但遇到了同样的问题。

我一直用pip所以这不是我熟悉的东西所以也许我做错了。任何帮助，我会永远感激，因为我认为我已经耗尽了所有资源。 （或者pyodbc 3.0.7的预构建副本也可以使用！）

您可能尝试使用默认Command Prompt进行构建。这不起作用。
您必须准备Command Prompt。我使用以下命令获取具有正确设置的命令行：
C:\Windows\System32\cmd.exe /E:ON /V:ON /T:0E /K "C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.cmd" /RELEASE /x64
您可以在桌面上创建一个新的快捷方式，这样您就不必在安装新的python模块时输入它。
现在，您可以运行新的Command Prompt并构建Python个包。

Python 3.4要求Visual Studio 2010编译像pyodbc这样的软件包，所以如果你安装了不同的版本，那肯定是个问题。只需重新安装Visual Studio，一切都应该正常工作！ https://www.microsoft.com/en-us/download/details.aspx?id=23691 如果您仍有问题，请考虑更改为3.5或3.6，这将很快出现！
希望它有所帮助， 斯塔姆
