visual-studio-2010 - 错误 : command 'cl.exe' failed: No such file or directory Python 3. 4

Question

我一直在尝试通过运行 python setup.py install 来安装 pyodbc 3.0.7，但问题仍然存在。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。我在网上查看的时间比我愿意承认的要长，试图弄清楚发生了什么。

我使用的是 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。

我运行的是 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

我已经重新启动了计算机，以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

从那里开始，作为最后的努力，我尝试清理和构建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，我将永远感激不已，因为我认为此时我已经用尽了所有资源。 (或者 pyodbc 3.0.7 的预构建副本也可以!)

您可能尝试从默认的命令提示符 构建。这是行不通的。

您必须准备一个命令提示符。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，这样当您想要安装一个新的 python 模块时就不必键入它了。

现在您可以运行一个新的命令提示符并构建一个Python包。
