应该配置什么以在端口80中启动独角兽。

最佳答案

尝试遵循有关此response的建议：


在我的deploy.rb文件中，设置以下行：

set :bundle_dir, "/usr/local/rvm/gems/ruby-X.X.X-pXXX"

在此行之前：

require 'bundler/capistrano'

似乎可以帮助打捆机知道将宝石安装在哪里。不知道为什么
这是必需的。我从来没有需要它。



编辑

在capistrano3上，如果使用gem rvm1-capistrano3，则可能需要对其进行更新，因为它是fixed issue：

bundle update rvm1-capistrano3

另外，您应该使用capistrano-unicorn的capistrano3 fork：


将库添加到您的Gemfile中：

group :development do
  gem 'sepastian-capistrano3-unicorn', :require => false
end

...并删除行

 gem 'capistrano3-unicorn'
