我使用brew install icu4cwithpip install pyicu来安装 python ICU 支持，但最后我无法在我的 Mountain Lion 上工作。

这是安装了 Xcode 4.5 和 46.DP2 的 Mountain Lion 设置。

有人遇到同样的问题吗？我还能尝试什么？

最后，我通过将icu4c版本降级到 4.8.1.1 使其工作。

$ brew uninstall icu4c

$ pip uninstall pyicu

$ brew versions icu4c
4.8.1.1  git checkout 3f0fb81 /usr/local/Library/Formula/icu4c.rb
50.1     git checkout 03ed757 /usr/local/Library/Formula/icu4c.rb
49.1.2   git checkout c25fd2f /usr/local/Library/Formula/icu4c.rb
4.8.1    git checkout 4ed0519 /usr/local/Library/Formula/icu4c.rb
4.4.1    git checkout c1e5cc2 /usr/local/Library/Formula/icu4c.rb

$ cd `brew --prefix`

$ git checkout 3f0fb81 /usr/local/Library/Formula/icu4c.rb

$ brew install icu4c

$ env LDFLAGS="-L/usr/local/opt/icu4c/lib" CPPFLAGS="-I/usr/local/opt/icu4c/include" pip install pyicu
