【问题描述】：

当我运行bundle install 时，出现以下错误。就像我运行bundle -v

/Library/Ruby/Site/2.0.0/rubygems/dependency.rb:318:in `to_specs': Could not find 'bundler' (>= 0) among 13 total gem(s) (Gem::LoadError)
Checked in 'GEM_PATH=/Users/john/.gem/ruby/2.0.0:/Library/Ruby/Gems/2.0.0:/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/gems/2.0.0', execute `gem env` for more information
    from /Library/Ruby/Site/2.0.0/rubygems/dependency.rb:327:in `to_spec'
    from /Library/Ruby/Site/2.0.0/rubygems/core_ext/kernel_gem.rb:64:in `gem'
    from /usr/local/bin/bundle:22:in `<main>'

这是我的红宝石环境

这里是which bundler

/usr/local/bin/bundler

【问题讨论】：

"Could not find bundler" error的可能重复
您的环境设置正确吗？你的 Gemfile 是什么样的？ rbenv 还是 rvm？
你的 binstubs 生成了吗？
我正在使用 el capitan 和 rbenv。当我输入哪个捆绑器时，我得到 /usr/local/bin/bundler 这里是 echo $PATH /usr/local/bin:/usr/local/sbin:/Users/john/.rbenv/shims:/Users/john/ .rbenv/bin:/usr/bin:/usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
你试过 gem install bundler 吗？

【解决方案1】：

原来 $PATH 设置不正确，bin 在 rbenv 前面。所以它选择了错误的捆绑器。这是现在的路径：

/Users/john/.rbenv/shims:/Users/john/.rbenv/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

在 local/bin 前面加上 .rbenv 一切都很好
