知道我仍然是 Rails 的初学者，要让 sqlite3 与 heroku 一起工作，我必须将它移动到我的 gemfile 中的开发和测试组中。

知道我仍然是 Rails 的初学者，要让 sqlite3 与 heroku 一起工作，我必须将它移动到我的 gemfile 中的开发和测试组中。
您需要为生产添加 pg gem。将 heroku 环境设置为生产环境。 heroku 不支持 sqlite3。
当我开始使用 heroku 和 rails 时，它发生在我身上。我认为问题在于您在将 pg gem 放入生产组之前部署了您的应用程序，现在由于某种原因即使添加了 gem 您仍然遇到问题。
可能的解决方案：
删除你的 Gemfile.lock 和 运行
bundle install --without=production
删除您在 heroku 上部署的应用程序并使用新 gemfile.lock 部署一个新应用程序。
我的解决方案：
我删除了 rails 应用程序并创建了一个新应用程序，这不是问题，因为我刚刚开始这个项目，但我了解到您必须配置 gem 文件和应用程序一般来说，在开始编码和部署之前，这是正确的方法。
在部署到 heroku 之前检查本教程的第一章以了解正确的配置：https://www.railstutorial.org
我在为我的新 rails 应用迁移 heroku 上的数据库时出错 这是我得到的错误

知道我仍然是 Rails 的初学者，要让 sqlite3 与 heroku 一起工作，我必须将它移动到我的 gemfile 中的开发和测试组中。
这是我的 gemfile：

知道我仍然是 Rails 的初学者，要让 sqlite3 与 heroku 一起工作，我必须将它移动到我的 gemfile 中的开发和测试组中。
您需要为生产添加 pg gem。将 heroku 环境设置为生产环境。 heroku 不支持 sqlite3。
当我开始使用 heroku 和 rails 时，它发生在我身上。我认为问题在于您在将 pg gem 放入生产组之前部署了您的应用程序，现在由于某种原因即使添加了 gem 您仍然遇到问题。
可能的解决方案：
删除你的 Gemfile.lock 和 运行
bundle install --without=production
删除您在 heroku 上部署的应用程序并使用新 gemfile.lock 部署一个新应用程序。
我的解决方案：
我删除了 rails 应用程序并创建了一个新应用程序，这不是问题，因为我刚刚开始这个项目，但我了解到您必须配置 gem 文件和应用程序一般来说，在开始编码和部署之前，这是正确的方法。
在部署到 heroku 之前检查本教程的第一章以了解正确的配置：https://www.railstutorial.org
