python - 在 Mac 上安装 pyqt (v4.8) 时出错

Question

检查后我尝试了“brew install pyqt” How to install PyQt on Mac OS X 10.6和一堆博客网站。具体来说，

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

但它因这个错误而失败了-

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

有人可以帮帮我吗？我看到 open-uri.rb 模块有问题，但我几乎没有使用 Ruby 的经验。

更新 Homebrew 软件为我消除了这个错误:

brew update
