我已经尝试更新捆绑器并安装它，但它仍然失败。我已经浏览了我能找到的关于这个主题的所有内容，但它并没有解决问题。
宝石文件：
source 'http://isitup.org/rubygems.org'
gem 'sinatra', '1.3.3'
gem 'thin'
gem 'warden'
gem 'bcrypt-ruby'
group :production do
gem 'pg'
end
group :development, :test do
gem 'sqlite3'
end
这就是我运行 git push heroku master 时发生的情况

You are trying to install in deployment mode after changing
your Gemfile. Run `bundle install` elsewhere and add the
updated Gemfile.lock to version control.
You have added to the Gemfile:
* warden
* bcrypt-ruby
* pg
* sqlite3

谢谢。
