部署到heroku时，与fontawesome的Rails编译器错误
当我尝试将我的Rails项目推送到Heroku时收到错误消息。 我正在使用Fontawesome，它在当地环境中完美运行，但不会推送到Heroku。

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
把这个gem放在你的gem文件中：
gem 'font-awesome-sass', '~> 4.5.0'
然后在application.scss中导入这些内容
@import "font-awesome-sprockets"; @import "font-awesome";
然后使用控制台bundle install gem。
然后（ 重要 ）在推送到Heroku之前使用rake在控制台中清理和预编译您的资产
rake assets:clean rake assets:precompile
现在，当您推送时，您的资产应该正确编译。
可能更容易使用：gem’font_awesome5_rails’
