我是 OneMonth 学习条纹支付的初学者 rails。现在，我正在学习如何创建产品 table 并为数据库播种。到目前为止一切都很顺利，直到我在 运行 rake db: seed

任务：TOP => db:seed
（使用 --trace 查看 运行 任务的完整跟踪）
我试过 rake db: reset，然后 rake:db migrate，然后再次 rake db: seed。但我仍然有同样的错误。
谁能帮我解决这个问题？我感觉卡住了，我不知道该怎么做。
非常感谢！
当你做 rake db:reset 时，rails 做的是 rake db:drop -> rake db:create -> rake db:migrate -> rake db:seed。
您不需要再rake db:seed。
您可以通过执行 rails c 检查您的控制台，看看您的种子数据是否已经在其中。 Product.all
'Email has already been taken' 表示您有一条包含相同电子邮件的记录。
执行 Rails 控制台并检查记录是否存在。
如果不是，则执行 rake db:drop -> rake db:create -> rake db:migrate -> rake db:seed。这将解决您的问题。
