Cli: db:migration doesn't work using .sequelizerc

[eharoldreyes]

What you are doing?

Hi All,
I'm trying to run a migration with my config defined to .sequelizrc but it throws me an Unhandled rejection TypeError using sequelize db:migrate command.

.sequelizerc
```const path = require('path');
const config = require(__dirname + '/config');
const cfg = {};
cfg[!process.env.NODE_ENV ? "development" : process.env.NODE_ENV] = config.MYSQL;
module.exports = {
'config': cfg,
'migrations-path': path.resolve(__dirname, 'sequelize/migrations'),
'seeders-path': path.resolve(__dirname, 'sequelize/seeders'),
'models-path': path.resolve(__dirname, 'models')
};

12345-migration file.js
```js
'use strict';
module.exports = {
    up: (queryInterface, Sequelize) => {
        return queryInterface.renameColumn('movement', 'timePerRep', 'timePerRepMillis');
    },
    down: (queryInterface, Sequelize) => {
        return queryInterface.renameColumn('movement', 'timePerRepMillis', 'timePerRep');
    }
};

What do you expect to happen?

I'm expecting that the migration will use the .sequezlizerc config file.

What is actually happening?

I believe that the CLI is reading the .sequelizerc but it is expecting a string instead of the config object.

Unhandled rejection TypeError: Path must be a string. Received { development:

'config': cfg, should be a path to file not configuration itself.

See http://docs.sequelizejs.com/manual/tutorial/migrations.html#dynamic-configuration this is how you can create a file which can return dynamic configuration. give that dynamic config file's path in .sequelizerc file

'config': cfg, should be a path to file not configuration itself.

This solution works! Thanks a lot, @sushantdhiman.

Have same issue with 4.0.0 version of cli.
Same error appears even if I provide string path to cli - I tried to use config.js file, but cli can't.
And same config.json file works :/
