can't seem to get the dialect to work, I'm getting this:

RROR: Dialect undefined does not support db:create / db:drop commands

Note: the "undefined".

My config.js for the babelHook.js looks like:

// migrations/config/config.js
import config from '../../config/config.json';
const env = process.env.NODE_ENV || 'development';

export default {
  [env]: {
    dialect: config[env]['dialect'],
    username: config[env]['username'],
    password: config[env]['password'],
    host: config[env]['host'],
    migrationStorageTableName: 'SequelizeMeta'
  }
};

Running it, such as...

$ npm run sequelize db:drop

> @2.10.0 sequelize /Users/gary/Development/digsup/DigsUp
> sequelize $* "db:drop"


Sequelize CLI [Node: 9.8.0, CLI: 4.0.0, ORM: 4.37.8]

Any help appreciated.

Resolved. The issue was actually that I needed to pass the environment variable through to babel.
I used cross-env, so this solved it by adding it to my package.json.

"sequelize": "cross-env NODE_ENV=local sequelize $*",

this doesn't actually work for me with import and export statements. i'm trying the following:

  • running ./node_modules/.bin/sequelize via ./node_modules/.bin/babel-node
  • requiring babel-core/register in my sequelize config.js
  • using cross-env (didn't help)

relevant npm run commands:

    "sequelize": "NODE_ENV=development ./node_modules/.bin/babel-node ./node_modules/.bin/sequelize --config config/sequelize-cli.js",
    "db:migrate": "npm run sequelize db:migrate",
    "db:seed": "npm run sequelize db:seed:all",

my sequelize config:

require('babel-core/register');

const path = require('path');
const conf = require(path.resolve('.', 'config'));

const env = conf.get('NODE_ENV');

console.log(`env=${env}, db config=`);
console.log(conf.get('db'));

module.exports = { [env]: conf.get('db') };

the tests:
