我有一个 Capistrano 脚本，它将我的应用程序部署到 Amazon EC2 机器上。编译资产时失败：

【解决方案1】：

将以下内容添加到 deploy.rb

require "bundler/capistrano"
require "rvm/capistrano"
before "deploy:assets:precompile", "bundle:install"

并跟随 Capfile

load 'deploy/assets'

并跟随 Gemfile

gem 'rvm-capistrano'

为我解决了这个问题。如果您不使用 rvm，也许您不需要 rvm/capistrano 或 rvm-capistrano gem。
