npm -v: 6.12.1

How

Current Behavior

npm run generates no output

Steps to Reproduce

On a command line (Windows "CMD.EXE"):
md npm-run-issue
cd npm-run-issue
npm init

Edit contents of package.json:

{ "name": "npm-run-issue", "version": "1.0.0", "description": "Minimal reproduction of npm run issue", "main": "index.js", "scripts": { "echo": "echo 'run' works!" }, "author": "", "license": "ISC" }

npm run echo

No output (at all) is generated.

Expected Behavior

Output should be similar to that from "yarn run":
yarn run v1.9.4
$ echo 'run' works!
'run' works!
Done in 0.12s.
