Rails 部署到 heroku 时 fontawesome 出现编译器错误

Question

当我尝试将我的 Rails 项目推送到 Heroku 时收到一条错误消息。我正在使用 Fontawesome，它在本地环境中运行良好，但不会推送到 Heroku。

Running: rake assets:precompile I, [2016-03-22T05:59:25.096354 #366] INFO -- : Writing /tmp/build_3e31f1bb8b828cb787890706e9ec589b/public/assets/FontAwesome-0d34da07e5cbcb4ff087b397966a9f9ffb4d6ed7c7060568565203c02f3fee11.otf I, [2016-03-22T05:59:25.099701 #366] INFO -- : Writing /tmp/build_3e31f1bb8b828cb787890706e9ec589b/public/assets/fontawesome-webfont-e511891d3e01b0b27aed51a219ced5119e2c3d0460465af8242e9bff4cb61b77.eot

Precompiling assets failed. ! ! Push rejected, failed to compile Ruby app

这是我的 gemfile：

source 'https://rubygems.org'

gem 'sprockets', '~> 3.0'
gem 'rails', '4.2.6'
gem 'pg', '~> 0.15'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc

group :development, :test do 
 gem 'byebug'
end

group :development do
  gem 'web-console', '~> 2.0'
  gem 'spring'
end

Answer 1

将此 gem 放入您的 gem 文件中：

gem 'font-awesome-sass', '~> 4.5.0'

然后将这些导入您的 application.scss

 @import "font-awesome-sprockets";
 @import "font-awesome";

然后 bundle install gem 使用控制台。

然后（重要）在推送到 Heroku 之前在控制台中使用 rake 清理和预编译您的资产

rake assets:clean
rake assets:precompile

现在你的资产应该在你推送时正确编译。

Answer 2

可能更容易使用：gem 'font_awesome5_rails'
