Mac OS X下让ruby支持tcl/tk

    我记得在老早在OS X10.8下使用ruby1.9.x的时候只要到下载安装ActiveTcl8.5，没怎么配置就运行tk好好的。但是近日想重新执行下tk代码，发现在require ‘tk‘的时候就报错鸟！现在用的是ruby2.1.3版本。上网搜了一下，1.9.x之后的版本默认不再将tcl/tk支持编译到ruby里面，so如果你想用则必须重新编译ruby！我勒个去！就不能做成个gem吗？但在多种外围尝试无果的的情况下只有一条路，就是重新编译ruby了...

    到ruby官网下载最新的ruby2.1.5的源代码15MB左右，解压后257MB，console进入解压目录，输入：

./configure -prefix=/Users/apple/src/ruby_src/ruby2.1.5_installed --with-arch=x86_64,i386 --enable-pthread --enable-shared --with-tk --with-tcl

注意-prefix必须要绝对路径，否则不让过；这是你要最后安装ruby2.1.5的路径，一旦固定下来，就不可以再动了。因为我后来用rvm也安装了ruby2.1.5版，所以这里换了个临时位置，只是测试用的。接着可以输入make命令编译ruby，大概要等一会，最后执行make install就将ruby2.1.5安装到了我前面设定的位置上。下面测试一下对tk的支持如何：

apple@kissAir: bin$ls

erb    gem    irb    rake   rdoc   ri     ruby   testrb

apple@kissAir: bin$./ruby -e "require ‘tk‘"

可以看到是ok的，然后运行一下我的tk.rb看一下效果（代码节选）：

界面丑是丑了点，不过后期可以再调整哦,关键是这段代码windows，linux，OS X下跑都没问题啊，轻松跨平台鸟：

还有一种办法是用rvm重新安装支持tcl/tk的版本：

rvm reinstall 2.1.5 --enable-shared --enable-pthread --with-tk --with-tcl

不过我试了一下，在brew update无限卡住了，所以才有了开篇的那一坨文章...

最后本猫觉得这样用不太爽，尤其是自己编译的irb用不了，因为其还是调用了rvm的路径。要替换也很容易，做软连接吧：

apple@kissAir: rubies$ls -lh

lrwxr-xr-x  1 apple  staff    35B 12 10 13:03 default -> /Users/apple/.rvm/rubies/ruby-2.1.5

drwxr-xr-x  8 apple  staff   272B 12 10 13:02 tmp_ruby-2.1.5

先把原来的ruby目录改名，然后将编译的路径加入即可，可以看到其版本号显示略有不同：
