Question

I\'m trying to setup an environment for a Node.js app. but I\'m getting this error every time.

\"NODE_ENV\" is not recognized as an internal or extern

Answer 1

Do this it will definitely work

"scripts": {
    "start": "SET NODE_ENV=production && node server"
}

Answer 2

For windows open git bash and try

NODE_ENV=production node app.js

Answer 3

process.env.NODE_ENV is adding a white space do this

process.env.NODE_ENV.trim() == 'production'

Answer 4

For those who uses Git Bash and having issues with npm run <script>,

Just set npm to use Git Bash to run scripts

npm config set script-shell "C:\\Program Files\\git\\bin\\bash.exe" (change the path according to your installation)

And then npm will run scripts with Git Bash, so such usages like NODE_ENV= will work properly.

Answer 5

Use win-node-env, For using it just run below command on your cmd or power shell or git bash:

npm install -g win-node-env

After it everything is like Linux.

Answer 6

If anyone else came here like me trying to find a solution for the error:

'env' is not recognized as an internal or external command

The reason I got this is that I was migrating an angular solution from a mac development machine over to a windows 10 desktop. This is how I resolved it.

1. run npm install --save-dev cross-env

2. go into my package.json file and change all the script references from env <whatever> to cross-env <whatever>

Then my commands like: npm run start:some_random_environment_var now run fine on Windows 10.
