Mac上的Ruby1.9-Rails还在加载1.8库吗?

所以,走吧 ruby --version 在命令行给我:

ruby 1.9.1p129 (2009-05-12 revision 23412) [i386-darwin9.7.0]

irb $: 变量,该变量显示搜索到的所有位置 require load 调用时,列表是Ruby1.8位置,它们是OEM Ruby安装的一部分!

test
/Library/Ruby/Site/1.8
/Library/Ruby/Site/1.8/powerpc-darwin9.0
/Library/Ruby/Site/1.8/universal-darwin9.0
/Library/Ruby/Site
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/powerpc-darwin9.0
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/universal-darwin9.0
.

内部评级 可执行文件仍然指向1.8,因此我确保shebang是正确的,它是:

#!/usr/local/bin/ruby

我想这没有什么内在的问题 在这些位置中搜索include,但看起来只有这些位置-它永远不会在lib/ruby19目录中搜索标准库。有什么好处?

更新

如果我有鲁比给我 $: 内部评级 看起来列表是正确的:

ruby -e 'puts $:'

/usr/local/lib/ruby19/1.9.1/test
/usr/local/lib/ruby19/gems/1.9.1/gems/actionmailer-2.3.2/lib
/usr/local/lib/ruby19/gems/1.9.1/gems/actionpack-2.3.2/lib
/usr/local/lib/ruby19/gems/1.9.1/gems/activerecord-2.3.2/lib

/usr/local/lib/ruby19/gems/1.9.1/gems/activesupport-2.3.2/lib
/usr/local/lib/ruby19/gems/1.9.1/gems/daemons-1.0.10/lib
/usr/local/lib/ruby19/gems/1.9.1/gems/eventmachine-0.12.8/lib
/usr/local/lib/ruby19/gems/1.9.1/gems/rack-1.0.0/bin
/usr/local/lib/ruby19/gems/1.9.1/gems/rack-1.0.0/lib
/usr/local/lib/ruby19/gems/1.9.1/gems/rails-2.3.2/bin
/usr/local/lib/ruby19/gems/1.9.1/gems/rails-2.3.2/lib
/usr/local/lib/ruby19/gems/1.9.1/gems/thin-1.2.2/bin
/usr/local/lib/ruby19/gems/1.9.1/gems/thin-1.2.2/lib
/usr/local/lib/ruby19/site_ruby/1.9.1
/usr/local/lib/ruby19/site_ruby/1.9.1/i386-darwin9.7.0
/usr/local/lib/ruby19/site_ruby
/usr/local/lib/ruby19/vendor_ruby/1.9.1
/usr/local/lib/ruby19/vendor_ruby/1.9.1/i386-darwin9.7.0
/usr/local/lib/ruby19/vendor_ruby
/usr/local/lib/ruby19/1.9.1
/usr/local/lib/ruby19/1.9.1/i386-darwin9.7.0
.

所以,这听起来像是错误的版本 正在调用。但正如我所说,shebang行似乎在与正确的Ruby可执行文件进行通信。

如果我调用 内部评级 具有 ruby 然后我就得到了1.9的正确列表,包括:

ruby /usr/local/bin/irb

这是 真正地
