推荐答案

感谢 RAJ 提醒我检查 database.yml 文件，我以某种方式为用户名设置了一个值，但我忘记了，默认情况下应该是 nil，所以我删除了用户名:taouan"，然后运行 ​​bundle exec rake test:prepare 它工作了.另一种方法是ALTER DATABASE testp00 OWNER TO "taouan"

Thanks RAJ for reminding me to check the database.yml file ,i put a value for username somehow and i forgot it, by default it should be a nil, So i deleted username: "taouan " then run bundle exec rake test:prepare it worked. Alternative way is ALTER DATABASE testp00 OWNER TO "taouan"
