Ruby アプリを作成していますが、プログラムを起動するときに大量の gem が必要です。元:
require "active_record"
require "RedCloth"
require "rchardet"
require "mailfactory"
require "net/smtp"
ただし、レールをインストールし、次のように上に置いてリストsudo gem install rails --version=2.1.1
に追加しようとすると:rails
require "rails"
require "rails"
require "active_record"
require "RedCloth"
require "rchardet"
require "mailfactory"
require "net/smtp"
私のアプリは次の行で壊れます: /usr/local/lib/site_ruby/1.8/rubygems/core_ext/kernel_require.rb:51:in `gem_original_require': no such file to load -- rails (LoadError)
gem list
Railsを実行すると、そこにあります:
emai@myserver:/usr/local/www/sl-exchange$ gem list
