“捆绑：找不到命令：瘦” Heroku的部署轨

Question

所以我的应用程序运行完全在我的本地机器上，我推它成功的GitHub和Heroku的，但是当我尝试在我的浏览器中打开应用程序时，我收到以下错误：

Application Error 
An error occurred in the application and your page could not be served. Please try again in a few moments. 

If you are the application owner, check your logs for details. 

然后我尝试运行

$ heroku logs 

而且我得到了我的控制台输出如下：

我找不出本作的是什么，因为这是我第一次部署到Heroku的，我不知道网络部署的任何东西。任何帮助将不胜感激！

Answer 1

你可能丢失你的Gemfile中的瑰宝。确保您的应用程序需要的所有内容都在Gemfile中指定，而不是在本地执行“gem install”。为了验证，你可以安装RVM，专门创建一个宝石为您的应用程序，运行“安装捆绑”在你的应用程序目录，然后看看你的应用程序在本地运行。如果它不运行，一个宝石肯定会丢失。

Answer 2

对我来说，问题是我在开发部分添加了瘦我的Gemfile，但是一旦我做了，那么heroku想用它来生产，但不会在开发部分安装宝石。通过移动薄宝石出来供所有环境中使用开发部分的，我能闯过此错误。

你的Gemfile可能会是这个样子的Rails应用程序：

source 'https://rubygems.org' 

gem 'rails' 
gem 'heroku' 

# Bundle edge Rails instead: 
# gem 'rails', :git => 'git://github.com/rails/rails.git' 

gem 'pg' 
gem 'thin' 

# more gems 

的Heroku recommends thin用于生产Web服务器反正。

更新（2012-05-16）：在该现在的Rails以上recommends unicorn的Heroku 3的网络服务器的链接。薄将仍然工作，但你可能要考虑switching over to unicorn。

Answer 3

看来，heroku正试图在没有Procfile的情况下启动Thin来告诉它。如上所述，Thin没有安装在Gemfile中，因此出现错误。如上所述，从开发小组中脱身是行得通的。

如果你想获得的Heroku开始独角兽，而不是薄，设置你的config/unicorn.rb和你Procfile如下所示：https://devcenter.heroku.com/articles/rails-unicorn

为麒麟Procfile内容中的链接上面列出的，并有关Procfile的更多信息（只是一个名为'Procfile'的文件在你的应用程序的根目录中）：https://devcenter.heroku.com/articles/procfile
