I'm getting this error when I try to migrate with node_modules/.bin/sequelize db:migrate

I think the mysql2 package causes this error

I'm appreciate for your help

First, please make sure your config.json does not contain any unquoted values like the password in this example:

{
 "my_env": {
    "username": "root",
    "password": 1234,
    "database": "my_db",
    "host"    : "localhost",
    "dialect" : "mysql"
  }
}

If that doesn't solve your problem and you have a strong reason to believe it has something to do with mysql2 package, try downgrading your sequelize package to v3 and which uses mysql rather than mysql2
