I just upgraded from Snow Leopard to Lion, and an old python c-extension that I had to update didn't want to compile properly. I don't really know what to do here. Anyone who could help me out so it compiles ok? It compiled just fine back in Snow Leopard.

Home:folder Me$ python setup.py build
running build
running build_ext
building 'ccookies' extension

您似乎使用的是 32 位 Python 2.7，可能是从 python.org 安装的。由于 Xcode 4 的变化（放弃对 10.4u SDK 和 gcc-4.0 的支持），在 10.7 Lion 上使用 Python 构建 C 扩展模块是不切实际的。使用 Apple 提供的 Python 2.7 ( /usr/bin/python2.7) 或为 2.7.2 安装python.org 64 位/32 位安装程序，而不是仅安装 32 位安装程序。

我试图在我的 Mac OS X 10.7 上安装 pynauty，但遇到了这个问题。由于某些原因，Ned Deily 的回答对我没有帮助。我只是想提供另一种方法来解决这个问题，以防有人来到这个页面并且与我处于相同的情况。我解决这个问题的方法是：

在运行“python setup.py build”之前，运行：export ARCHFLAGS="-arch x86_64"

在 travis 上，我遇到了这个错误。从那以后我一直在使用osx_image: osx10.11，但在过去的几周内，它突然停止工作，出现这个错误。更改osx_image: xcode7.3为我修复了错误。
