获取错误：在部署/迁移到Heroku时更新rubygems
迁移到Heroku时出现以下错误。
Installing hoe (2.9.4) /usr/ruby1.9.2/lib/ruby/1.9.1/rubygems/installer.rb:170:in >install’：hoe需要RubyGems版本> = 1.4。 尝试’gem update –system’来更新RubyGems本身。 （gem:: InstallError）`
这就是rubygem版已经过时了。 有人知道我怎么能解决这个问题？
使用rails 3.0.5和ruby 1.9.2

好的，我解决了。
锄头根本无法使用heroku，因为它们不支持新版本的rubygems（这对heroku来说是一种痛苦）
我在这里添加了锄头gem：
group :test, :development do gem "hoe" end
并在我的控制台中输入以下内容：
heroku config:add BUNDLE_WITHOUT="development:test"
