我第一次使用 SQLite3 从本地 Rails 环境部署到使用 postgresql 的 Heroku。我已经更新了我的 gemfile 以制定适当的开发/生产组条款。我确保将这些更改包含在主文件中。但是，当我运行 db:push 时，我反复收到以下错误

非常感谢您的帮助

要使heroku db:push命令正常工作，您需要在Ruby Heroku 捆绑包的版本中同时安装taps和gems。sqlite3

从上面的回溯中，似乎taps已安装，但缺少sqlite3适配器。

要安装它，请尝试以下操作：

  • Program Files启动提升的命令提示符（这样您就可以毫无问题地写入
  • cd "C:\Program Files (x86)\Heroku\ruby-1.9.2\bin"目录。
  • 调用gem install sqlite3 --no-ri --no-rdoc

那应该安装缺少的 gem 并允许heroku db:push使用您的 sqlite3 数据库。

希望有帮助。
