Capistrano Rails Assets 预编译错误

Question

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 Assets 时失败:

* executing "cd -- /home/ec2-user/uc_social_server/releases/20130731161645 && RAILS_ENV=production RAILS_GROUPS=assets rake assets:precompile"
    servers: ["ec2-23-22-188-11.compute-1.amazonaws.com"]

Answer 1

将以下内容添加到 deploy.rb

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

并跟随到 Capfile

load 'deploy/assets'

并关注 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。
