你可以發佈database.yml – RAJ 2014-09-01 17:59:02

嗨剛發佈，謝謝你c – Snailwalker 2014-09-01 18:01:28

哈哈我只是想通了，有一個用戶名。「taouan」 – Snailwalker 2014-09-01 18:04:29

感謝RAJ提醒我檢查database.yml文件，我爲用戶名設置一個值，我忘了它，默認情況下它應該是一個零，所以我刪除用戶名：「taouan」然後r它的工作原理是bundle exec rake test:prepare。替代方法是ALTER DATABASE testp00 OWNER TO "taouan"

在用戶名後面什麼都不用：解決我的問題，起初我沒有用戶名和密碼：並且導致錯誤。 – 2016-09-16 05:00:49
