NodeJs：dotenv不适用于嵌套路径

Question

I have react project with my own custom file structure. Here is an image for the project structure.

My index.js

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import dotenv from 'dotenv'
dotenv.config({path:'../.env'});
console.log(process.env)
ReactDOM.render(<App />, document.getElementById('root'));

.env

API_URL = http://54.254.198.83:1441/

console output

{NODE_ENV: "development", PUBLIC_URL: ""}

Why are the .env variables not added to process.env ?

Answer 1

This is how you get dotenv working with nested paths:

require('dotenv').config({path:'relative/path/to/your/.env'})

Place this at the top of the file you want your .env vars available within.

Answer 2

Try directly setting environmental variables without dotenv

Set variables when running your application.

API_URL = "http://54.254.198.83:1441/" npm start
