“...无法弄清楚...的架构类型”使用 gcc 编译 Python C 扩展时出现问题
我刚刚从 Snow Leopard 升级到 Lion，我必须更新的旧 python c 扩展不想正确编译。我真的不知道在这里做什么。任何人都可以帮助我，使其编译正常吗？它在 Snow Leopard 中编译得很好。

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 中的更改（放弃了对 10.4u SDK 和 gcc-4.0 的支持），在 10.7 Lion 上使用该 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) 或安装 python.org 2.7.2 的 64 位/32 位安装程序，而不是仅 32 位的安装程序。You appear to be using a 32-bit Python 2.7, possibly installed from python.org. Because of changes in Xcode 4 (dropping of support for the 10.4u SDK and gcc-4.0) it is not practical to build C extension modules with that Python on 10.7 Lion. Either use the Apple-supplied Python 2.7 (
/usr/bin/python2.7) or install the python.org 64-bit/32-bit installer for 2.7.2 instead of the 32-bit-only one.我试图在 Mac OS X 10.7 上安装 pynauty，但遇到了这个问题。由于某些原因，内德·戴利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，以防有人来到此页面并且遇到与我相同的情况。我解决这个问题的方法是：
在运行“python setup.py build”之前，运行：
导出 ARCHFLAGS="-arch x86_64"
I was trying to install pynauty on my Mac OS X 10.7 and I got this problem. For some reasons, Ned Deily's answer didn't help me. I just want to provide one more way to solve this problem in case someone come to this page and is in the same situation as I am. The way I solved this prolem is:
Before running "python setup.py build", run:
export ARCHFLAGS="-arch x86_64"
在 travis 上，我遇到了这个错误。我一直在使用 osx_image: osx10.11 ，但在过去几周内它突然停止工作，并出现此错误。更改为 osx_image: xcode7.3 为我修复了错误。
On travis, I was getting this error. I've been using
osx_image: osx10.11since forever, but it suddenly stopped working, with this error, in last ~few weeks. Changing toosx_image: xcode7.3fixed the error for me.
