Sinat的应用程序部署到Heroku失败了

时间：2018-03-22 19:22:01

标签： heroku deployment sinatra

这是一个简单的2页Sinatra应用程序，Heroku会返回以下错误消息。

我尝试将config.ru和app.rb置于app folder和根路径下方 但两者都不起作用......

我错过了什么吗？

答案 0 :(得分：0)

我刚做了测试，写了一个非常简单的Sinatra应用程序并将其推送到Heroku。

的Gemfile 

source 'https://rubygems.org'

ruby '2.4.0'
gem 'sinatra'

config.ru 

require './app'
run Sinatra::Application

app.rb 

require 'sinatra'

get '/' do
  "Hello world"
end

此时启动rackup在本地完美运行，但是当我推送到heroku时，我也遇到了错误，就像你一样。看起来我错过了Procfile。然后我添加了一个简单的Procfile来告诉Heroku运行应用程序时应该启动什么：

Procfile 

web: bundle exec rackup config.ru -p $PORT

所以在这一点上，我得到了这个文件层次结构：

App directory
 \ 
  |– Gemfile
  |– config.ru
  |– app.rb
  |– Procfile

而且，它现在完美无缺。可能值得一试并将这种Procfile添加到您的项目中。您可以在Heroku Getting started on Heroku with Ruby : Procfile及其devcenter article about process types and Procfiles上找到有关Procfile的更多详细信息。
