nodemon 未加载环境变量

Question

The following is in my gulpfile.js :

const nodemon = require('nodemon')

const server = nodemon({
    script: './src/index.js',
    ext: 'hbs json js css',
    require: 'dotenv/config',
    dotenv_config_path: './config/.env',
    stdout: false // without this line the stdout event won't fire
})

I am looking to duplicate the exact same behavior as the dev script in the package.json file:

  "scripts": {
    "test": "jest --watch",
    "dev": "nodemon -r dotenv/config ./src/index.js dotenv_config_path=./config/.env -e js,hbs,json,css",
    "debug": "nodemon --inspect -r dotenv/config ./src/index.js dotenv_config_path=./config/.env -e js,hbs,json,css"
  },

For one reason or another it seems that gulp is not registering the environment variables defined in the .env file. Although the line below works just fine when ran with npm run dev :

nodemon -r dotenv/config ./src/index.js dotenv_config_path=./config/.env -e js,hbs,json,css

You may need to add export to your environment vars and load them before running nodemon :

vars.env

export ENV_FIRST="J"
export ENV_LAST="Doe"

package.json

"scripts": {
  "dev": "source vars.env; nodemon ..."
  ...
}
