Heroku的应用程序无法启动 - “需要”：没有这样的文件加载 - sinatratestapp（LoadError） [英] Heroku app fails to start - `require': no such file to load -- sinatratestapp (LoadError)

问题描述

我试图让我的Heroku应用程序使用 bamboo-mri-1.9.2 堆栈运行。当然，它在Ruby 1.9.2本地运行良好。但在生产过程中，它会在执行 config.ru 时看起来像这样崩溃：

I'm trying to get my Heroku app to run using the bamboo-mri-1.9.2 stack. Of course it's running fine locally on Ruby 1.9.2. But when on production it crashes during the startup on executing config.ru which looks like this:

require 'sinatratestapp'
run Sinatra::Application

我的 .gems file：

sinatra --version '>= 1.0'

而应用程序本身为 sinatratestapp.rb ：

require 'rubygems'
require 'sinatra'

get '/' do
  "Hello from Sinatra on Heroku!"
end

这就是我在项目中所做的一切，并试图在Heroku上运行它结果：

That's all I've got in the project and trying to run that on Heroku results:

<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- sinatratestapp (LoadError)
        from <internal:lib/rubygems/custom_require>:29:in `require'
        from config.ru:1:in `block (3 levels) in <main>'
        ...
-----> Your application is requiring a file that it can't find.

       Most often this is due to missing gems, or it could be that you failed
       to commit the file to your repo.  See http://docs.heroku.com/gems for
       more information on managing gems.

       Examine the backtrace above this message to debug.

我尝试过，但是作为Ruby noob，我的考试没有任何结果。 / p>

I've tried to do as it guides but as a Ruby noob my examinations have resulted nothing.

推荐答案

Ruby 1.9.2不会自动包含。在$ LOAD_PATH中。要解决这个问题，通过声明 require'./sinatratestapp'而不是来修改 config.ru 需要'sinatratestapp'。

Ruby 1.9.2 doesn't automatically include "." in the $LOAD_PATH. To workaround this, modify config.ru by stating require './sinatratestapp' instead of require 'sinatratestapp'.
