irb 使用 rbenv 加载错误的 ruby 和 gem 路径
我开始使用 rbenv 进行 ruby 版本管理，我发现 irb 没有加载正确的 ruby 版本和 gem 版本。以下是详细信息。
irb Gem.path 说：
`>> Gem.path
=> ["/Users/Air/.gem/ruby/1.8", "/Library/Ruby/Gems/1.8", "/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8"]`
现在在 irb 中，如果我输入： puts $:
`>> puts $:
/Library/Ruby/Site/1.8
/Library/Ruby/Site/1.8/powerpc-darwin11.0
/Library/Ruby/Site/1.8/universal-darwin11.0
/Library/Ruby/Site
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/vendor_ruby/1.8 /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/vendor_ruby/1.8/universal-darwin11.0
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/vendor_ruby
/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-darwin11.0
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/universal-darwin11.0`
在 shell 中输入： gem env
`RubyGems Environment:

我可以看到 < strong>irb正在加载错误的Ruby版本并加载错误的Gem路径。有人可以帮助理解我该如何解决这个问题吗？我正在使用 rbenv 进行 ruby 版本管理，不确定它是如何发挥作用的。建议？
I started using rbenv for ruby version management and I'm finding that irb not loading the correct ruby version and gem version. Here are the details.
irb Gem.path says:
`>> Gem.path
=> ["/Users/Air/.gem/ruby/1.8", "/Library/Ruby/Gems/1.8", "/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8"]`
Now in irb if I type: puts $:
`>> puts $:
/Library/Ruby/Site/1.8
/Library/Ruby/Site/1.8/powerpc-darwin11.0
/Library/Ruby/Site/1.8/universal-darwin11.0
/Library/Ruby/Site
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/vendor_ruby/1.8 /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/vendor_ruby/1.8/universal-darwin11.0
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/vendor_ruby
/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-darwin11.0
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/universal-darwin11.0`
In the shell I type: gem env
`RubyGems Environment:

I can see that irb is loading the wrong Ruby version and loading the wrong Gem path. Can someone help understand how do I fix this. I am using rbenv for ruby version management not sure how that plays into things. Advice?

确保您正确设置路径并在您使用的 shell 中初始化 rbenv。
我已将以下几行添加到我的 .bash_profile 中：
我遇到了您所展示的问题，直到我记得这样做。
还要记住设置 ruby 的全局 rbenv 版本
Make sure you are setting your path correctly and initializing rbenv in the shell you are using.
I've added the following lines to my .bash_profile:
I had the problems you are exhibiting until I remembered to do this.
Also remember to set your global rbenv version of ruby
使用 rbenv 安装 ruby 后。
您是否使用命令
$ rbenv rehash重建了 shim 二进制文件
Once installed ruby using rbenv.
Have you rebuilded the shim binaries using the command
$ rbenv rehash
