it could not be found.

cabal: Error: some packages failed to install:
pango-0.12.3 failed during the configure step. The exception was:
ExitFailure 1

pkg-config通过Homebrew安装：

peauters:~ $ which pkg-config
/usr/local/bin/pkg-config
peauters:~ $ pkg-config --version
0.25

关于这个问题的想法？

Answer 1

这个错误有点令人困惑。

这就是说你需要安装非阴谋包“pango”。

我用brew install pango做了这个并解决了这个问题。

Answer 2

对于ubuntu，请参阅http://www.haskell.org/haskellwiki/Gtk2Hs/Linux，其中包含

sudo apt-get install libgtk2.0-dev libpango1.0-dev libglib2.0-dev libcairo2-dev
