npm ERR! Missing script: start

Question

I have this error when trying to start Vue-cli. The installation ran smoothly:

villas:vue villas$ npm start
npm ERR! missing script: start

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/villas/.npm/_logs/2017-08-25T00_39_17_837Z-debug.log

And there in the log file:

Answer 1

npm ERR! Missing script: start

This error occurs you did not set in the file package.json the script start, example:

  "scripts": {
    // Adicione essa linha, mas pode ser também ex = "start: "node index.js"
    "start": "vue init",
    "test": "echo "Error: no test specified" && exit 1"
  },

I recommend reading of package.json understanding the scripts article written by: William Brune
