ruby - 要求 ruby​​gems 在 irb 中工作但在脚本中不工作

Question

我有 Ubuntu 9.04 ruby 1.8Rubygems 1.3.5

在 irb 中，

irb(main):002:0> require 'rubygems'
=> true

在脚本中

$ ./test.rb 
./test.rb:2:in `require': no such file to load -- rubygems (LoadError)
from ./test.rb:2

$ gem environment
RubyGems Environment:
  - RUBYGEMS VERSION: 1.3.5
  - RUBY VERSION: 1.8.6 (2009-08-04 patchlevel 383) [i686-linux]

  - REMOTE SOURCES:

$ which ruby
/usr/local/bin/ruby

我认为这可能与我的 PATH 有关，但我不确定如何修复或修复什么。

我的 $LOAD_PATH 变量似乎有 gem 目录的路径。

$ gem env gemdir
/usr/local/lib/ruby/gems/1.8
$ irb
irb(main):001:0> $LOAD_PATH
=> ["/usr/local/lib/ruby/site_ruby/1.8", "/usr/local/lib/ruby/site_ruby/1.8/i686-linux", "/usr/local/lib/ruby/site_ruby", "/usr/local/lib/ruby/1.8", "/usr/local/lib/ruby/1.8/i686-linux", "."]

检查$LOAD_PATH，这个变量包含当您使用require 时ruby 查找的路径。
