我正在尝试将我的应用推送到heroku，但我一直在收到错误。我看到heroku不支持sqlite3，我从gem文件中删除它，然后捆绑。我的database.yml文件正在使用postgresql。也许其他东西试图使用sqlite？我该如何解决这个问题？以下是以下命令后heroku的日志。

答案 0 :(得分：0)
我之前在similar post回答了这个问题。做一个简单的搜索就可以得到答案，而不是马上询问。无论如何，这是解决方案。
只需在你的Gemfile中执行此操作
group :production do
gem 'pg'
gem 'rails_12factor'
end
并将您的sqlite3 gem转移到
group :development, :test do
gem 'sqlite3'
end
运行bundle install --without production，你应该好好去。在尝试推送到Heroku之前，请记得将新代码推送到git。
