[Vuejs]-Npm run build causes Error:This is probably not a problem with npm. There is likely additional logging output above

Maybe to give some insight on the Topic.

npm run “build” calls the script via command line defined in the package.json at the scripts object:

"scripts": {
"build": "cross-env NODE_ENV=production webpack --progress --hide-modules"
},

It looks like that the cross-env command is not recognized as command therefore i suggest you install Crossenv from npm, if not already done so
Depending on your OS other steps might be necessary.

npm install --save-dev cross-env

In my sanario I was not having VUE JS CLi installed on to my server thus

// to install vue on ubuntu
npm install -g @vue/cli
// check if it was installed successfully
vue --version
@vue/cli 4.1.2

After that you can build VUE app

 npm install 
 npm run build

Usualy it means that you need run npm install before build your application.

Try this way:

 $ npm install 
 $ npm run build
