在Mac上安裝pyqt（v4.8）時出錯

Question

在檢查了如何在Mac OS X 10.6上安裝PyQt和一堆博客后，我嘗試了“brew install pyqt”。 Specifially，

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

但它失敗了這個錯誤 -

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

有人可以幫幫我嗎？ 我看到open-uri.rb模塊有問題，但我幾乎沒有使用Ruby的經驗。

更新自制軟件為我擺脫了這個錯誤：

brew update
