如何在Heroku上升级系统宝石？

Question

我在 Heroku 的 bamboo-mri-1.9.2 栈上运行，并在将代码推送到 Heroku 时收到以下消息：我被难住了：

  Installing hoe (2.9.1) /usr/ruby1.9.2/lib/ruby/1.9.1/rubygems/installer.rb:170:in `install': hoe requires RubyGems version >= 1.4. Try 'gem update --system' to update RubyGems itself. (Gem::InstallError)

有什么想法吗？谢谢您的帮助。

也许将此作为对Heroku的支持请求提交会更好。我相信您无法访问更新Heroku系统gem，也许我是错误的。 - nzifnab

我会从你上传到github的内容中排除'hoe'宝石。

group :test, :development do
  gem "hoe"
  # other gems you want to exclude from github
end

然后在你的Heroku变量中设置：

heroku config:add BUNDLE_WITHOUT="development:test"

在哪里添加上述代码？？？group :test, :development do gem "hoe" # 其他你想要从 Github 排除的 gem end - ish

这是一个聪明的解决方法，但它并没有回答最初的问题。 :/ - NilsHaldenwang

尝试使用不同版本的 how：

hoe 2.10.0 
hoe 2.9.6 
hoe 2.9.5 
hoe 2.9.4 
hoe 2.9.3 

一个接一个地添加它们，打包，然后推送到Heroku。
