我试图在heroku上发布我的演示应用程序（来自ruby教程），但我遇到错误的git push heroku master实现错误：

（此外，应用程序在azure虚拟机上启动，没有任何错误） 我已经尝试单独安装sqllite（成功），但即使安装了sqllite后我也有同样的错误：（
Gemfile中的sqlite3 gem：
gem 'sqlite3', '1.3.10'
答案 0 :(得分：3)
在你的gemfile中添加gem＆＃39; pg＆＃39;作为生产组，因为heroku支持postgresql
group :development do
gem 'sqlite3'
end
group :production do
gem 'pg'
end
并添加adapter: postgresql您的database.yml
production:
adapter: postgresql
encoding: unicode
database: database_name_production
答案 1 :(得分：2)
Heroku不支持sqlite3，因此它不会有安装sqlite3 gem所需的库文件。
您需要将sqlite3添加到Gemfile中的开发块，以便在部署期间不会安装它。
group :development do
gem 'sqlite3'
end
另外，请注意使用postgresql确保应用程序按预期运行。就个人而言，我建议使用相同类型的数据库进行开发，以便在将应用程序转移到生产环境时不会有任何意外。
