我有一个工作的centOS服务器，据我所知，它带有puppet所需的ruby 1.8.7，根据我的作品devops团队，我正在使用需要ruby 1.9+的Sinatra应用程序，他们拒绝使用RVM或rbenv，并坚持为 puppet 保留 1.8.7，因此他们从源代码安装了 1.9.3

/opt/ruby-1.9.3/bin/ruby

对于我的用户，我必须在我的 .bash_profile 中创建一些别名

alias ruby="/opt/ruby-1.9.3/bin/ruby"
alias gem="/opt/ruby-1.9.3/bin/gem"
alias erb="/opt/ruby-1.9.3/bin/erb"
alias bundle="/opt/ruby-1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.5/bin/bundle"
alias rackup="/opt/ruby-1.9.3/lib/ruby/gems/1.9.1/gems/rack-1.5.2/bin/rackup"

ruby 可以工作，gem 也可以，但从来没有捆绑器或 rackup，我必须使用普通的 gem install 安装我的 Sinatra 应用程序依赖项，这对我来说没问题。

但是现在我想通过 apache 和乘客 (mod_rails) 为应用程序提供服务，我收到关于未找到 gems 的错误，例如：

Could not find nokogiri-1.5.9 in any of the sources (Bundler::GemNotFound)

当我尝试使用捆绑器时，我收到此错误：

$ bundle install
/opt/ruby-1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.5/bin/bundle:7:in `require': no such file to load -- bundler (LoadError)
    from /opt/ruby-1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.5/bin/bundle:7

第 7 行文件的内容是：

require 'bundler'

有什么线索吗？提前致谢！

我在这里大错特错，指向 bundle 和 rackup 的别名指向了不正确的路径，它们最终是这样的：

alias ruby="/opt/ruby-1.9.3/bin/ruby"
alias gem="/opt/ruby-1.9.3/bin/gem"
alias erb="/opt/ruby-1.9.3/bin/erb"
alias bundle="/opt/ruby-1.9.3/bin/bundle"
alias rackup="/opt/ruby-1.9.3/bin/rackup"

可能将两个 ruby​​ 版本放在一起的别名方法不是最好的方法（记住这里没有 RVM 或 rbenv），但现在可以使用
