Answer 1

Reading though the error you provided, it mentions that it during your build process, it expected another key-value pair on line 17 of package.json.
I ran your package.json through a JSON and found a few issues, as follows -
Parse error on line 11: You should remove the line break between lines 11 and 12.
"unit": "cross-env BABEL_ENV=test karma start test / unit / karma.conf.js--single - run ",
Parse error on line 14:: You should remove the line break between lines 14 and 15.
"lint": "eslint --ext .js,.vue src test/unit/specstest / e2e / specs ",
Parse error on line 15:: You should remove the comma, since this is the last property of scripts.
"start": "node server.js"
Duplicate key 'start' on line 15:: *You need to decide whether you want your start script to be
"start": "node build/dev-server.js", OR "start": "node build/dev-server.js",
Fixing these should solve your build errors.
Corrected package.js file
