如何在 Mac OS X 8.5（Mountain lion OS）中安装 pyodbc

Question

尽管多次尝试，我还是无法构建从 Google 代码页面下载的 pyodbc 模块。

它失败并显示以下错误消息

这是我正在使用的 xcode 版本

BHUKRK263339D:pyodbc-master Minat_Verma$ xcode-select --version xcode-选择版本 2311。

我有什么遗漏吗？ ?

Answer 1

您尚未安装 Xcode 命令行工具。

您可能可以使用以下命令来完成：

$ xcode-select --install

否则您可能必须从 Xcode 本身安装它们。
