所以，当我推送到我以前没见过的heroku时，我遇到了一个错误。我正在积极尝试了解错误的含义，以便我可以解决它。
我看到我的sqlite3存在问题但仍无法解决问题。搞砸了我的宝石文件，然后花了几个小时让它回到当地工作，我来这里寻求帮助。
非常感谢任何输入！

Heroku使用postgresql数据库，因此从gem文件中删除 sqlite3 或将其移至开发组并添加 gem＆＃39; pg＆＃39; 到你的宝石文件。关于 database.yml 设置，请按照此Heroku setup

确保已从Gemfile中删除sqlite3 gem并运行bundle install。
如果你继续收到这个错误，请检查你的Gemfile.lock作为一些gems列出sqlite3作为依赖项 - 你也想要删除这些gems。
