我正在尝试运行一个过去运行良好的 Ruby脚本.我需要使用Mechanize gem,因此在脚本的顶部,它表示需要’mechanize’.但是,当我尝试现在运行脚本时,终端输出显示: /Users/codebiker/.rvm/rubies/rub
/Users/codebiker/.rvm/rubies/ruby-2.1.0/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- mechanize (LoadError) from /Users/codebiker/.rvm/rubies/ruby-2.1.0/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in `require' from myscript.rb:2:in `<main>'
当我按照这里的建议运行gem env时,我得到:
RubyGems Environment: - RUBYGEMS VERSION: 2.2.1 - RUBY VERSION: 2.1.0 (2013-12-25 patchlevel 0) [x86_64-darwin13.0] - INSTALLATION DIRECTORY: /Users/codebiker/.rvm/gems/ruby-2.1.0 - RUBY EXECUTABLE: /Users/codebiker/.rvm/rubies/ruby-2.1.0/bin/ruby - EXECUTABLE DIRECTORY: /Users/codebiker/.rvm/gems/ruby-2.1.0/bin - SPEC CACHE DIRECTORY: /Users/codebiker/.gem/specs - RUBYGEMS PLATFORMS: - ruby - x86_64-darwin-13 - GEM PATHS: - /Users/codebiker/.rvm/gems/ruby-2.1.0 - /Users/codebiker/.rvm/gems/ruby-2.1.0@global - GEM CONFIGURATION: - :update_sources => true - :verbose => true - :backtrace => false - :bulk_threshold => 1000 - :benchmark => false - :sources => ["http://rubygems.org/", "http://gemcutter.org"] - "install" => "--no-rdoc --no-ri" - "update" => "--no-rdoc --no-ri" - REMOTE SOURCES: - http://rubygems.org/ - http://gemcutter.org - SHELL PATH: - /Users/codebiker/.rvm/gems/ruby-2.1.0/bin - /Users/codebiker/.rvm/gems/ruby-2.1.0@global/bin - /Users/codebiker/.rvm/rubies/ruby-2.1.0/bin - /usr/local/bin - /usr/bin - /bin - /usr/sbin - /sbin - /usr/local/bin - /opt/X11/bin - /usr/texbin - /Users/codebiker/.rvm/bin
当我运行rvm get head时,我得到:

当我运行哪个ruby时,我得到:
/Users/codebiker/.rvm/rubies/ruby-2.1.0/bin/ruby
而ruby -v给了我:

任何建议,想法或提示将不胜感激!我不知道这里有什么问题.
必须首先安装Gems,然后才能在脚本中要求它们.安装宝石;首先打开一个终端窗口然后键入:gem安装GEM-NAME或在你的情况下:gem install mechanize
