irb加载错误的ruby和gem路径,使用rbenv

Question

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.这是详细信息.

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中我输入:gem env

`RubyGems Environment:  
  - RUBYGEMS VERSION: 1.8.10

我可以看到irb正在加载错误的Ruby版本并加载错误的Gem路径.有人可以帮助了解我该如何解决这个问题.我使用rbenv进行ruby版本管理,不确定它是如何发挥作用的.建议吗？

Answer 1

确保正确设置路径并在正在使用的shell中初始化rbenv.

我在.bash_profile中添加了以下行:

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

我记得你遇到的问题,直到我记得这样做.

还记得设置ruby的全局rbenv版本

Answer 2

一旦使用rbenv安装ruby.

您是否使用该命令重建了填充二进制文件

$ rbenv rehash
