Mysql2 ::错误：拒绝用户'test'@'localhost'访问数据库'depot_test'

因此，首先以 root 身份登录或从终端调用任何root用户。

mysql -u root -pCREATE DATAbase depot_testCREATE USER 'test'@'localhost' IDENTIFIED BY 'mypass123';USE depot_test

登录到mysql后，向用户授予特权

test

GRANT ALL privileges on depot_test.* to test@localhost identified by 'mypass123';FLUSH PRIVILEGES;

您将需要在数据库.yml中将通行证更改为“ mypass123”
