python - 在 MacOSX 上编译coverage.py 时出错

Question

我尝试安装coverage 3.4在运行当前 Mac OS X 10.6.7 的 MacBook 上。这是我得到的错误:

$ easy_install coverage
install_dir /Users/jammon/workspace/myproject/lib/python2.7/site-packages/

有人能从中理解吗？我根本不明白出了什么问题。或者我该如何解决它。
非常感谢任何帮助。

更新:
在 Ned 发表评论后，我尝试使用 easy_install -vv cover ；结果差别不大:

据我记得，我以标准方式从源代码编译了 python，它不是二进制发行版。我尝试了使用和不使用 virtualenv 的情况。

最新版本的 XCode 取消了对编译到旧 PowerPC (PPC) 架构的支持。不幸的是，Mac 上的 Python 通常仍然尝试为 PPC 和 x86 构建 C 扩展。要解决此问题，请在“setup.py install”或“easy_install”等命令前加上仅包含您要为其构建的体系结构的 ARCHFLAGS 设置:

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