我正在尝试将我的应用程序推送到 heroku。我输入 git push heroku 并返回：
git push heroku

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 deleted from the Gemfile:
* factory_girl_rails (= 4.2.1)

我已经多次将 factory_girl_rails 添加和删除到 gemfile 中，并与它一起运行 bundle install 。
我已经尝试按照它给出的指示进行操作，但我无法让它发挥作用。
我不确定问题是什么，但它不会推到heroku。
任何人都可以帮忙吗？
这是我的宝石文件：
source 'https://rubygems.org'
ruby '2.0.0'
#ruby-gemset=railstutorial_rails_4_0
gem 'rails', '4.0.1'
gem 'bootstrap-sass', '2.3.2.0'
gem 'devise'
group :development, :test do
gem 'sqlite3', '1.3.8'
gem 'rspec-rails', '2.13.1'
end
group :test do
gem 'selenium-webdriver', '2.35.1'
gem 'capybara', '2.1.0'
gem 'factory_girl_rails', '4.2.1'
end
gem 'sass-rails', '4.0.1'
gem 'uglifier', '2.1.1'
gem 'coffee-rails', '4.0.1'
gem 'jquery-rails', '3.0.4'
gem 'turbolinks', '1.1.1'
gem 'jbuilder', '1.0.2'
group :doc do
gem 'sdoc', '0.3.20', require: false
end
group :production do
gem 'pg', '0.15.1'
gem 'rails_12factor', '0.0.2'
end
这就是我的 Gemfile 中 factory_girl_rails 的样子。
