编译时出错覆盖率.py在MacOSX上

Question

我试图在运行当前macosx10.6.7的MacBook上安装coverage 3.4。这是我的错误：

有人能理解吗？我只是不明白怎么了。或者我如何解决它。
非常感谢任何帮助。在

更新：
在内德的评论之后，我用easy_install -vv coverage尝试了一下；结果没有太大不同：

最新版本的XCode取消了对编译到旧的PowerPC（PPC）体系结构的支持。不幸的是，Mac上的Python通常仍然试图为PPC和x86构建C扩展。为了解决这个问题，可以使用前缀命令，比如'设置.py“安装”或“轻松安装”，ARCHFLAGS设置仅包括要为其生成的体系结构：

ARCHFLAGS="-arch i386 -arch x86_64" easy_install coverage

经过大量的google搜索，我在this blogpost and the comments中找到了一个对我有用的解决方案：我删除了/Developer/SDKs/MacOSX10.4u.sdk，然后安装coverage（和reportlab，它显示了相同的问题）正如预期的那样工作。在

据我所知，在gcc的某些版本中，stdarg.h的处理发生了变化，导致了所描述的问题。在

或者，您可以use ActivePython来避免compile things yourself的需要：

$ pypm install coverage
The following packages will be installed into "~/Library/Python/2.7" (2.7):
 coverage-3.4
Get: [pypm-free.activestate.com] coverage 3.4
Installing coverage-3.4                                  
Fixing script ~/Library/Python/2.7/bin/coverage
