error on "scripts" > "start"

[vqueja]

I am using this setup in my package.json:

"name": "angularspree",
"version": "0.0.1",
"license": "MIT",
"scripts": {
"ng": "./node_modules/@angular/cli/bin/ng",
"start-mock": "ng serve -H 0.0.0.0 --environment=mock",
"start": "cd dist && ../node_modules/live-server/live-server.js --port=8081 --host=localhost --entry-file=/index.html",
"build": "ng build",
"test": "echo 'no test'",
"lint": "",
"e2e": "node e2e/home.js",
"compodoc": "./node_modules/.bin/compodoc -p src/tsconfig.app.json -d docs/",
"build--prod": "ng build --prod --no-sourcemap --stats-json && npm run sw",
"sw": "sw-precache --root=dist --config=sw-precache-config.js",
"static-serve": "cd dist && live-server --port=8081 --host=localhost --entry-file=/index.html"

During deployment, it fails due to this error:

angularspree@0.0.1 start /var/app/current
cd dist && ../node_modules/live-server/live-server.js --port=8081 --host=localhost --entry-file=/index.html

This has not happened before though.
