Node-Sass is not recognized as an internal command

Question

I’m trying to create a command for compile scss in css more easily.

I followed this tutorial

I installed nodejs, npm and Node-Sass

I got into my project and ran the remote

npm init

My package.json looks like this:

{
"name": "piattino",
"version": "1.0.0",
"description": "Documenação do site piattivo.com.br",
"main": "index.js",
"scripts": {
  "test": "echo \"Error: no test specified\" && exit 1",
  "scss": "node-sass -watch scss -o css"
},
"author": "",
"license": "ISC"
}

after that I circled the command:

npm run scss

and then I get the following mistake:

> [email protected] scss C:\Users\bruno\projetos\piattino
> node-sass -watch scss -o css

'node-sass' n▒o ▒ reconhecido como um comando interno
ou externo, um programa oper▒vel ou um arquivo em lotes.

You need to install Node-Sass globally:

npm install -g node-sass

Or add it to your package.json as a dependency:

"devDependencies": {
    "node-sass": "^4.9.0"
},

And then execute:

npm install --save-dev node-sass

Your script is also incomplete, it should be like this:

"scss": "node-sass -watch -include-path scss -o css"

The -include-path sets the folder where the files scss are, and the -o is the output folder of your compiled file.

Node-Sass to run windows needs some C++ components, install this guy: https://www.microsoft.com/pt-br/download/details.aspx?id=48145 and see if it solves.
