Ruby on Rails 应用程序 Heroku 部署问题

Question

我在将我的应用程序启动到 Heroku 时遇到问题。我目前正在学习 Ruby on Rails 教程第 1 章，但遇到以下错误：

 1. remote:  remote: -----> Ruby app detected remote: -----> Compiling
    Ruby/Rails remote: -----> Using Ruby version: ruby-2.0.0 remote:
    -----> Installing dependencies using bundler 1.9.7 remote:        Running: bundle install --without development:test --path
    vendor/bundle --binstubs vendor/bundle/bin -j4 --deployment remote:

    Push rejected, failed to compile Ruby app remote:  remote: Verifying
    deploy... remote:  remote: !       Push rejected to stark-dusk-2366.

我是新手，不太了解文件结构或我应该用来解决此问题的命令。

您是否像错误所说的那样运行了 bundle install ？发生了什么？ 另外，请查看 Heroku guide 以设置 Rails，这对我有很大帮助。
