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 external command,
operable command or batch file.

What does this mean and how can I solve this problem?

I’m using Windows and also tried set NODE_ENV=development but had no luck.

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 was not clear how/when you executed it.
