Ruby on rails 如何加快Heroku上的coffee脚本资产编译

Ruby on Rails 3.2有很多小的coffee脚本文件，需要花费大量的时间来部署：

有没有办法加快Heroku上的资产编译

选项1：本地预编译资产

您可以在本地编译资产，将其添加到源代码管理并将其推送到Heroku：

RAILS_ENV=production bundle exec rake assets:precompile
git add public/assets
git commit -m "Precompile assets"

Heroku随后将检测预编译的资产并跳过编译

-----> Preparing Rails asset pipeline
       Detected manifest.yml, assuming assets were compiled locally

有关更多信息，请参阅

选项2：对链轮使用memcache缓存

Via（免责声明：我没有尝试过这种方法。）

启用memcache加载项

heroku addons:add memcachier

将

dalli

和

memcachier

添加到您的GEM文件中

在

config/environments/production.rb中配置资产缓存存储

config.assets.cache_store = :dalli_store

这意味着资产是git的一部分，我不确定是否要这样做。我已经更新了答案，添加了第二个选项（还没有尝试过）
