我第一次推向Heroku的使用Git，我得到的错误信息： Gemfile.lock is required. Please run "bundle install" locally and commit your Gemfile.lock. Gemfile.lock is required. Please run "bundle install" locally and commit your Gemfile.lock.
我已经跑了bundle install ，添加文件到git回购，COMMITED的变化。 见Gemfile.lock在仓库中，我的目录既但是当我运行命令git push heroku master它始终抛出错误。
我究竟做错了什么：
这是我的电脑上的混帐回购协议
$git ls-files
.bundle/config
.gitignore
.rspec
Gemfile
Gemfile.lock
README
Rakefile
app/assets/images/rails.png
app/assets/javascripts/application.js
app/assets/stylesheets/application.css
..<snip>..
这里是回购的git的状态。
$git status
# On branch ch_ruby_intro
# Your branch is ahead of 'origin/ch_ruby_intro' by 6 commits.
#
nothing to commit (working directory clean)
当我尝试部署错误。
$git push heroku master

为什么没有看到Gemfile.lock的文件吗？
