Question

我无法通过保存的脚本加载任何宝石，但是在irb中一切似乎都运行良好：

$ irb
irb(main):001:0> require 'nokogiri'
=> true
irb(main):002:0> exit
$ cat test.rb
require 'rubygems'
require 'nokogiri'
require 'active_record'
$
$ ruby test.rb
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- nokogiri (LoadError)
        from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
        from test.rb:2
$
$ gem list --local

Answer 1

我刚刚安装了rvm，即使在我的默认ruby安装上，一切都突然正常工作。我猜这解决了。

Ruby gems无法在脚本中加载，但在irb中加载正常
