ruby - Lion OSX : How to install libfreetype. 6.dylib？

Question

我正在尝试安装 ruby​​ gem，但安装过程已停止，因为:

ld: file not found: /usr/local/lib/libfreetype.6.dylib for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

如何安装这个库？我检查了 /usr/local/lib/ 并且那里缺少库。

编辑:

我运行 locate libfreetype.6.dylib 并得到:

但为什么系统找不到图书馆？

您要安装什么库？它可能是 ImageMagick 吗？另外，如果它是一个 RubyGem，为什么帖子被标记为 homebrew？

无论如何，我在安装 ImageMagick 时遇到了这个错误，你需要将 /opt/X11/lib/libfreetype.6.dylib 符号链接(symbolic link)到 /usr/local/lib .

这样做:

ln -s/opt/X11/lib/libfreetype.6.dylib/usr/local/lib/libfreetype.6.dylib
