Go to your_app/ config/database.yml and in username insert your MySQL username (ex. Root) and in password your MySQL password. 转到your_app / config / database.yml，在用户名中输入您的MySQL用户名（例如Root），并在密码中输入MySQL密码。 Don't forget to fill also the field "database". 不要忘记也填写“数据库”字段。

The error is caused by wrong credentials. 该错误是由错误的凭据引起的。 You must set database_name, user_name and password. 您必须设置数据库名称，用户名和密码。
