git push heroku主机不工作

我尝试了“bundle install”命令和“bundle update”，但似乎没有任何效果。

下面的部分如何：

I am trying to push my code to heroku and this appears as an error:
-----> Ruby app detected
-----> Compiling Ruby/Rails
-----> Using Ruby version: ruby-2.0.0
-----> Installing dependencies using 1.7.12
       Running: bundle install --without development:test --path vendor/bundle --binstubs vendor/bundle/bin -j4 --deployment

Git中是否包含Gemfile.lock

and add the updated Gemfile.lock to version control
