在Mac上安裝pyqt（v4.8）時出錯

Question

在檢查 How to install PyQt on Mac OS X 10.6和一堆blogsites後，我嘗試了「brew install pyqt」。

clang: error: linker command failed with exit code 1 (use -v to see invocation) 
make[2]: *** [../../lib/QtCore.framework/QtCore] Error 1 
make[1]: *** [release] Error 2 
make: *** [sub-corelib-make_default-ordered] Error 2

是否有人可以幫助我 - Specifially，

> brew install qt --with-developer --env=std 

但與此錯誤失敗了嗎？我發現open-uri.rb模塊存在問題，但我幾乎沒有使用Ruby的經驗。

更新自制擺脫了這個錯誤對我說：

brew update
