Node-sass is not recognized by command line

Question

I'm trying to set up node-sass, following the instructions on CSS-Tricks. Node and npm are installed correctly, and the node-sass installation worked too. When I go to run node-sass --output-style compressed -o dist/css src/scss, though, I get an error message stating

'node-sass' is not recognized as an internal or external command, operable program or batch file.

I've done a fair bit of Googling and searched Stack Overflow directly. My question isn't about "node" not being recognised as a command. I know node is working as I can run node -v and npm -v, and node-sass was successfully installed after running npm install --save-dev node-sass (there's a folder in node_modules) and no errors appeared in the command line.

Other information: I am running Windows 10 and just did a clean install of node and npm before trying to use node-sass.

EDIT: I uninstalled and reinstalled with -g thanks to @Bhavik's suggestion, and it's now working

Answer 1

You need to install it globally

npm install -g node-sass

Or add it in package.json

"devDependencies": {
    "node-sass": "4.5.0"
},
"scripts" : {
    "node-sass": "node-sass --output-style compressed -o dist/css src/scss"
}

And then do
1. npm i, which in this case would be similar to npm install --save-dev node-sass
2. npm run node-sass

Reference: npm scripts, npm-run-scripts

Answer 2

You can simply run this code

1. npm install -g sass
2. sass --watch sass:css

Hopefully work

Answer 3

npm commands check "node_package" folder and try to run things there. You can try

npx run scss 

to install scss and then run it, even if it is not installed before.

Answer 4

The below solves the problem

yarn global add node-sass-chokidar

Answer 5

This is a simple problem don't worry too much. Just go to package.json file and add this code

"devDependencies": {
    "node-sass": "4.9.2"
},
"scripts" : {
    "node-sass": "node-sass --output-style compressed -o dist/css/ scss --recursive"
}

and just save the file.

And run this command,

npm run node-sass

That's all

Answer 6

node-sass v4.13+

1. Install node-sass in your project locally

cd <root path of your project>
yarn add -D node-sass
// or
npm install -D node-sass

2. Add a script to your package.json

"scripts" : {
...
  "compile:sass": "node-sass --recursive --watch <sass directory> --output <css directory>",
...
}

3. Run the script from the command line

yarn compile:sass
// or
npm run compile:sass

Answer 7

First, run npm install -g node-sass as others have pointed out.

Now, the target of the command (sass.cmd) is not located in the current working directory. For it to still be able to run, its location must be in your PATH (or Path) environment variable.

For me, the path is: C:\Users\Guy\AppData\Roaming\npm

Make sure to restart any terminal/IDE you were trying to run it in before trying again. Otherwise it won't recognize the new environment variable.
