我是Ruby on Rails的新手，也是一般的编程新手，因此我无法阅读此日志并了解问题。我刚刚在Rails中创建了一个简单的应用程序，我正在尝试将其推送到Heroku。我知道sqlite和Heroku存在问题，所以我将我的gem文件更改为：
source 'https://rubygems.org'
gem 'rails', '4.0.2'
gem 'sass-rails', '~> 4.0.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 1.2'
gem 'bootstrap-sass'
group :development, :test do
gem 'sqlite3'
end
group :production do
gem 'pg'
gem 'rails_12factor'
end
group :doc do
gem 'sdoc', require: false
end
然后我运行了bundle install - 没有生产。然后我通过命令行将它推送到git和heroku。它似乎工作，但当我进入页面heroku创建我收到此消息：应用程序错误 应用程序中发生错误，无法提供您的页面。请稍后再试。
如果您是应用程序所有者，请查看日志以获取详细信息。
然后我运行了heroku logs --tail并得到了这条消息。
我无法弄清楚导致问题的原因。我只用了大约两天的时间来编程或Rails，所以这很令人困惑。谢谢。

这一行看起来很可疑：
/app/vendor/bundle/ruby/2.
0.0/gems/font-awesome-less-4.1.0/lib/font_awesome/less.rb:33:in `require': canno
t load such file -- less-rails (LoadError)
font-awesome-less似乎不在您的gem文件中，您应该将其添加为依赖项。
gem 'font-awesome-less'
有关使用详情，请参阅this。
顺便说一句，less和sass或多或少相同，我可能会选择一个并坚持使用它（字体 - 真棒 - 更少取决于你已经拥有sass-rails的更少你的宝石文件）。 font-awesome-rails等同于font-awesome-less。

除了hjing发布的精彩答案之外，这是阻止您推送到Heroku的主要错误：
错误：无法将某些引用推送到 'git@heroku.com：tranquil-earth-2932.git'提示：更新被拒绝 因为你当前分支的提示背后提示：它的远程 对方。整合远程更改（例如提示：'git pull ...'） 在再次推动之前。
该错误基本上表示您的remote git repo领先于本地。要解决这个问题，如评论中所述，我会：
$ git add .
$ git commit -a -m "Heroku"
$ git pull heroku master # -> this will just merge any of the "ahead" files
$ git add .
$ git commit -a -m "Heroku"
$ git push heroku master
-
<强> SASS
然后你有SASS错误来处理
要解决此问题，您需要能够使用font-awesome-less gem解决问题。下面的答案可以帮助你
