我想運行一個以前能正常工作的Ruby腳本。我需要使用機械化寶石,所以在腳本的頂部,它說require 'mechanize'
。然而,當我嘗試現在運行腳本,終端輸出寫着:Ruby腳本無法找到所需的寶石
/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>'
當我運行gem env
,這裏建議,我得到:

任何意見,想法或建議,將不勝感激!我不知道這裏有什麼問題。
可能太明顯了,寶石是否安裝正確? –
輸入cmd'gem install mechanize' – fyz
