Heroku数据库:拉错误"LoadError:无法加载这样的文件-- sqlite3 (Sequel::AdapterNotFound)“

Question

我可以从我的MacBook开发环境中运行heroku db:pull，没有任何问题，但是当我在Windows7机器上执行该命令时，我得到了以下错误

Answer 1

您可能需要安装sqlite3 gem。

Answer 2

我遇到了同样的问题。我已经添加了sqlite3 gem，但我错误地将后续适配器称为sqlite3。正确的适配器名称就是sqlite。

Answer 3

我会试着安装几个gem：

gem install sqlite3
gem install heroku
