你可以发布database.yml – RAJ 2014-09-01 17:59:02

嗨刚发布，谢谢你c – Snailwalker 2014-09-01 18:01:28

哈哈我只是想通了，有一个用户名。 “taouan” – Snailwalker 2014-09-01 18:04:29

感谢RAJ提醒我检查database.yml文件，我为用户名设置一个值，我忘了它，默认情况下它应该是一个零，所以我删除用户名：“taouan”然后r它的工作原理是bundle exec rake test:prepare。替代方法是ALTER DATABASE testp00 OWNER TO "taouan"

在用户名后面什么都不用：解决我的问题，起初我没有用户名和密码：并且导致错误。 – 2016-09-16 05:00:49
