在我的Mac Air上，用pip安裝一些Python庫時，偶爾就會遇到一些報錯，關(guān)于“unused-command-line-argument-hard-error-in-future”，錯誤如下：
clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future]
clang: note: this will be a hard error (cannot be downgraded to a warning) in the future
error: command 'cc' failed with exit status 1
這樣的錯誤，出現(xiàn)次數(shù)多了，每次都去google，不如自己記錄一下吧。
原因是：The Apple LLVM compiler in Xcode 5.1 treats unrecognized command-line options as errors. This issue has been seen when building both Python native extensions and Ruby Gems, where some invalid compiler options are currently specified.
解決方法：設(shè)置ARCHFLAGS參數(shù)，如下:
