推送到heroku时,Ruby 2.0/Rails 4.0.0beta升级失败

Question

大脑倾倒,因为我的谷歌用谷歌搜索并在电脑上猛击我的头.任何帮助或线索将非常感谢!

我通过rvm管理我的宝石.

$ ruby -v
ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-darwin12.2.0]

$ rails -v
Rails 4.0.0.beta1

然后,当我想从头开始创建一个全新的应用程序

$ rails new brand_new_app
 create  
  create  README.rdoc
  ...
Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

$ cd brand_new_app

然后我初始化一个git repo,添加我刚创建的应用程序.然后我创建一个heroku实例

brand_new_app $ heroku create
    Git remote heroku added

然后我尝试部署到heroku但它在活动支持gem上失败.

brand_new_app $ git push heroku master

   Make sure that `gem install activesupport -v '4.0.0.beta1'` succeeds before
   bundling.
     !

我已经破坏了rvm(idk为什么,主要是因为我很沮丧)而且我已经检查过每一个可能的地方.我创建了rails应用程序,没有任何特殊设置,它只是一个正常的安装.如果有人有任何可以引导我走向正确方向的提示,请按我的方式发送给他们!我很感激你读到这里!

您应该在Gemfile中放置一个ruby行,就像heroku文档中所解释的那样.

只需在Gemfile中添加ruby "2.0.0"下面的行source "https://rubygems.org".

https://blog.heroku.com/archives/2012/11/5/ruby-2-preview-on-heroku

我试过这个,这适用于heroku.显然Rails 4与不同的ruby版本不兼容.这有点奇怪,因为他们在这里说:

Ruby 2.0是与Rails 4.0一起使用的首选Ruby.

http://weblog.rubyonrails.org/2013/2/25/Rails-4-0-beta1/

显然是首选,意味着需要.

希望这可以帮助
