我已经尝试了几个小时来安装Helm，我无法弄明白。我按照这里的说明进行操作：http://helm-engine.org/guide/installing/。其全部输出位于底部。我遇到过几个与我的问题here和here类似的案例，但解决方案不起作用。有没有办法在OS X Yosemite上安装Helm？

helm-0.6.0 depends on cairo-0.13.0.5 which failed to install.
pango-0.13.0.4 depends on cairo-0.13.0.5 which failed to install.

你的问题在这里：
Configuring cairo-0.13.0.5...
setup: Package xcb-shm was not found in the pkg-config search path.
Perhaps you should add the directory containing `xcb-shm.pc'
to the PKG_CONFIG_PATH environment variable
Package 'xcb-shm', required by 'cairo', not found
如果您已安装XQuartx，则所需文件（xcb-shm.pc等）位于/opt/X11/lib/pkgconfig。
我首先设置了cairo和pango：
export PKG_CONFIG_PATH=/opt/X11/lib/pkgconfig:/usr/local/lib/pkgconfig
更新
我尝试针对helm-0.6.0构建pango-0.13.0.3时出现编译错误。这就是我最终能够成功构建的方式：
helm.cabal并将glib添加到第一个build-depends部分src/FTP/Helm.hs进行以下编辑：
paFamily = textTypeface更改为paFamily = stringToGlib textTypeface import System.Glib.UTFString (stringToGlib) 答案 1 :(得分：0)
除了user5402所说的，你还需要手动安装sdl2-1.2.0。最新版本（1.3.0）目前与helm不兼容。
