The npm module cross-env was made exactly for this purpose. The way you set an environment variable is not same across all the OSes. cross-env solves this.

process.env.SOME_KEY = "somevalue";

  • You can use cross-env - npmjs.com/package/cross-env
  • try this SOME_KEY=abc npm start
  • I just tried this and it worked fine for me. Two things to try are (1) console.log(process.env) will show you all environment variables and (2) post your node code here so we can see exactly what's going on.
