无法在Capistrano 3的80号端口启动我的Unicorn

Question

尝试运行时出现以下错误

“cap production unicorn：start”

应该配置什么来启动端口80中的独角兽。提前感谢

请尝试遵循此response的建议：

  

在我的deploy.rb文件中，设置此行：

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

     

在此之前：

require 'bundler/capistrano'

     

似乎有助于捆绑商知道安装宝石的位置。不知道为什么   这是必要的。我以前从未需要它。

<击> 的修改

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

bundle update rvm1-capistrano3

此外，您应该使用capistrano-unicorn的{​​{3}}：

  

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'
