我安装git的使用是 brew install git的方式安装的。最近安装git后发现gitk打不开了
报了以下error info：
Error in startup script: unknown color name "lime"
    (processing "-fore" option)
    invoked from within
"$ctext tag conf m2 -fore [lindex $mergecolors 2]"
    (procedure "makewindow" line 347)
    invoked from within
"makewindow"
    (file "/usr/local/bin/gitk" line 12434)

解决方法是：brew cask install tcl，Keith B solved this problem,this is the origin answer:

You can check your version of Tcl/Tk by running wish and using the command info patchlevel. It appears that git 2.7.0, Tcl/Tk 8.5.9, and OS X 10.11 El Capitan do not work well together.
I solved this problem by doing brew cask install tcl, which installed 8.6.4, and gitk works now.

最后不知道brew 命令安装软件的可以看一下我的这篇博客：http://blog.youkuaiyun.com/natural_story/article/details/50580820
