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

npm install -S cross-env

Worked for me

Answer 2

For windows you can do it like

"scripts": {
    "start:prod" : "SET NODE_ENV=production & nodemon app.js",
    "start:dev" : "SET NODE_ENV=development & nodemon app.js"
},

Answer 3

I wrote a module for this: win-node-env.

It creates a NODE_ENV.cmd that sets the NODE_ENV environment variable and spawns a child process with the rest of the command and its args.

Just install it (globally), and run your npm script commands, it should automatically make them work.

npm install -g win-node-env

Answer 4

set NODE_ENV=production & nodemon app/app.js

will cause NODE_ENV to contain a space at the end:

process.env.NODE_ENV == 'production'; //false
process.env.NODE_ENV == 'production '; //true

As mentioned in a comment here, use this instead:

NODE_ENV=production&& nodemon app/app.js

Answer 5

Most of the answers up there didn't help me..

What helped me was NODE_ENV=production&& nodemon app/app.js

Take note of the space. Good luck.

Answer 6

It sounds like your error comes from an attempt to run something like this (which works in Linux)

NODE_ENV=development node foo.js

the equivalent in Windows would be

SET NODE_ENV=development
node foo.js

running in the same command shell. You mentioned set NODE_ENV did not work, but wasn't clear how/when you executed it.
