Question

我对Ruby很新，我试图将我的代码推送到Heroku，但似乎当我尝试时：

git push heroku master

推送失败并显示此错误：

   error: failed to push some refs to 'git@heroku.com:testapp.git'

这是我向Heroku提交push命令后显示的内容。我认为这是因为我在这里的gem文件中的代码：

gem 'rails', '4.1.6'
group :development, :test do 
    gem 'sqlite3'
end
gem 'sass-rails', '~> 4.0.3'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'y
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0',          group: :doc
gem 'spring',        group: :development
gem 'devise'
gem 'simple_form'

有人可以帮我这个吗？

Answer 1

目前，您将sqlite3 gem放在development和test组中。如果您想在Heroku上使用sqlite3进行部署，则还需要将其包含在生产组中，这与删除group :development, :test一样简单。

请注意，在Heroku上使用sqlite3很可能是一个坏主意，你最好使用Heroku Postgres。 Read the Heroku documentation for more information

Answer 2

经过一段时间的搜索，我看到了答案

 http://ryanbigg.com/2014/10/ubuntu-ruby-ruby-install-chruby-and-you//

我只需安装PG然后再做

sudo apt-get install libpq-dev

然后推送到heroku工作

heroku第一次推送遇到一个错误，拒绝我试图做的推
