如何避免从 process.env 文件中获取错误数据？

Question

I need to get some data from a.env.local file,however instead of getting the data of the file on the current folder i get the one from another project that i had made. How can I make node recognise the right file to read? example:

folder-structure:

folder:
   file.js
   .env.local

js file:

   const envData ={
      test1: process.env.TEST_1,
      test2: process.env.TEST_2,
      test3: process.env.TEST_3,
    })

.env.local file:

TEST_1=test1-data
TEST_2=test2-data
TEST_3=test3-data

The problem is:I don't get the data from the env file in my folder but from another one,how do I fix this?

I'd recommend using dotenv to manage your environment variables -- it loades environment variables from a .env file into process.env . So you'll have your .env file within your project folder and then whichever folder you need to load your env variables in, you'll require and configure the package at the top of the file like so: require('dotenv').config();

Which will allow you to call your env variables like process.env.XXX .
