Deployment on Heroku

[Traumaxp 0]

Hi, since this morning I meet issue when push to heroku.
Nothing has changed in my code, but now I have:

remote: -----> Build
remote:        Running build
remote:        
remote:        > tokengrowth@0.0.1 build
remote:        > quasar build
remote:        
remote: sh: 1: quasar: not found
remote: npm ERR! code 127

Yesterday, it was going well with this package.json:

my server.js

const express = require('express'),
      serveStatic = require('serve-static'),
      history = require('connect-history-api-fallback'),

port = process.env.PORT || 5000

const app = express()

app.use(history())
app.use(serveStatic(__dirname + '/dist/spa'))
app.listen(port)

I tried to add this:

"heroku-postbuild": "npm install --only=dev --no-shrinkwrap && npm run build"

but same issue.
