应该配置什么以在端口 80 中启动独角兽。提前致谢

尝试遵循response:

的建议

在我的 deploy.rb 文件中，设置这一行：

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

在这一行之前：

require 'bundler/capistrano'

似乎帮助捆绑者知道在哪里安装 gems。不知道为什么 这是需要的。我以前从来不需要它。

编辑

在 capistrano3 上，如果您使用 gem rvm1-capistrano3，您可能需要更新它，因为它是 fixed issue：

bundle update rvm1-capistrano3

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

将库添加到您的 Gemfile：

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

...并删除该行

 gem 'capistrano3-unicorn'
