在MacOSX上編譯coverage.py時出錯

Question

我試圖在當前Mac OS X 10.6.7上運行的MacBook上安裝coverage 3.4。這是我得到的一個錯誤：

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

有沒有人可以從這個意義上嗎？我根本不明白什麼是錯的。或者我可以如何解決它。
任何幫助非常感謝。

更新：
在Ned的評論後，我試着用easy_install -vv coverage;結果是沒有太大的不同：

至於我記得，我編譯Python從源的標準方式，它不是一個二進制分發。我嘗試過，沒有virtualenv。

Answer 1

最新版本的XCode取消了對編譯爲舊PowerPC（PPC）體系結構的支持。不幸的是，Mac上的Python通常仍然試圖爲PPC和x86構建C擴展。爲了解決這個問題，前綴的命令，如與ARCHFLAGS設置只包括要建立的體系結構「的setup.py安裝」或「的easy_install」：

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

Answer 2

或者，您可以use ActivePython以避免需要compile things yourself：

$ 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 
$ 

Answer 3

經過大量谷歌上搜索我的發現this blogpost and the comments的解決方案，爲我工作：我取下/Developer/SDKs/MacOSX10.4u.sdk，然後安裝覆蓋（和ReportLab的，這顯示了同樣的問題）按預期工作。

就我所知，stdarg.h的處理在gcc的某個版本中已經改變，導致所描述的問題。
