我正在关注本教程http://installfest.railsbridge.org/installfest/deploy_a_rails_app并且我总是失败，因为步骤2.2：准备你的rails应用程序以部署到Heroku ，我对 Gemfile进行了所有更改：
在此文件中，更改行：
gem 'sqlite3'
对此：
group :development, :test do
gem 'sqlite3'
end
group :production do
gem 'pg'
gem 'rails_12factor'
end
保存文件。
输入后：捆绑安装 - 无需生产
得到这个：

就是这样，我是新人，所以我真的不知道如何解决这个问题
答案 0 :(得分：1)
虽然如果您按照教程进行操作，我会按照Heroku directly
中的说明进行操作首先打开您的Gemfile并删除此行：
gem 'sqlite3'
替换为此行：
gem 'pg'
然后运行bundle install
答案 1 :(得分：0)
首先尝试bundle install --without production并将更改提交给git，然后尝试将您的工作重新推送到heroku。
