The process does not end after the completion of the custom environment variable packaging.

[zhayes]

The environment variable is configured to define the interface address

let baseUrl = 'http://test-xxx.com';

if(process.env.NODE_ENV === 'production') baseUrl = 'http://xxx.com';

But after packaging , the process does not end;

Although my environment variable is not production, my command is build, so should end the process.

My project was deployed online through shell scripts, but your process was not closed, and I could not tell if the packaging was finished.

Hope to solve it quickly.

Same issue here using yarn 1.7.0. Just upgraded to parcel 1.9.3.

"scripts": {
  "build": "parcel build index.html --no-cache --public-url=/"
}

Running yarn build works as expected.
Running NODE_ENV=qa yarn build builds, but the process hangs.

Edit: Added version numbers.
