从 Heroku 中排除 hoe gem 依赖项答案

【问题标题】：Exclude hoe gem dependency from Heroku从 Heroku 中排除 hoe gem 依赖项

【问题描述】：

我正在尝试将代码推送到 Heroku，似乎系统 gem“锄头”以某种方式被其他一些 gem 包含（geokit 是其中之一，但即使从 Gemfile 中删除了该 gem，也没有运气）。这导致 Heroku 失败，因为它无法更新系统 gem。如何解决这个问题？

Installing geokit (1.5.0) 
   Installing geonames (0.2.2) 
   Installing hoe (2.9.1) /usr/ruby1.8.7/lib/ruby/site_ruby/1.8/rubygems/installer.rb:170:in `install': hoe requires RubyGems version >= 1.4. Try 'gem update --system' to update RubyGems itself. (Gem::InstallError)

！ Heroku 推送被拒绝，无法通过 Bundler 安装 gems

【解决方案1】：

只需将其固定在您的 Gemfile 中，我敢打赌您的依赖 gem 不依赖于 2.9.1。添加这个：

gem 'hoe', '~> 1.5.1' # Heroku's rubygems is too old for hoe 2.9.1 as of 28 Mar 2011
