在windows上开发，在heroku上运行独角兽

问题描述

我有一个新的Rails项目，我决定给Heroku一个尝试，部署似乎很容易在那里

我在windows上开发，所以运行独角兽不是但是webrick对于开发很好

但是，当部署时，我想使用独角兽，而且heroku完全支持这个

问题是：我必须在我的Gemfile上列出独角兽，以便让heroku选择它，但是当我这样做并在Windows开发机器上运行bundle命令（或rails s）时，它会尝试安装独角兽服务器

我试图把独角兽放入制作组中，
group：production do
gem'unicorn'
end
仍捆绑抱怨，我无法运行开发服务器

解决方案

您可以在Gemfile中定位特定平台：

 平台：ruby do＃linux 
 gem'独角兽'
结束
 
平台：mswin做
＃gems特有的风ows 
 end

I have a new Rails project and i decided to give heroku a try, deployment seems very easy there

I am developing on windows, so running unicorn is not a choice, but webrick is fine for development

BUT, when it come to deployment , i want to use unicorn, and heroku perfectly support this

The Problem Is: i have to list unicorn on my Gemfile in order for heroku to pick it, but when i do that and run bundle command (or rails s) on my windows dev machine, it tries to install the unicorn server

i tried to put unicorn in the production group, group :production do gem 'unicorn' endstill bundle complain and i cannot run the dev server

解决方案

You can target specific platforms in your Gemfile:

platforms :ruby do # linux
  gem 'unicorn'
end

platforms :mswin do
  # gems specific to windows
end

see the manpages for gemfile for more information.
