Can't install node-sass

Question

I am attempting to install node-sass and it just won't let me. I have tried updating npm.

I put this in:

sudo npm install -g node-sass

and i get this (starting one line before the error):

gyp verb build dir attempting to create "build" dir:

Answer 1

For me, the error was solved when downgrading node to version 14 (I was on version 16). The tool mentioned in the following answer helped me switch quickly between node versions: https://stackoverflow.com/a/50287454/13005312

Answer 2

I had something similar going on, if nothing from above helps you try to remove the proxy first.
I had an npm ERR! code ECONNREFUSED issue while trying to install node-sass, so check in your logs if this is happening to you.
If a proxy exists remove it with this command:

npm config set proxy null
npm config set https-proxy null

next, set npm to download from the official package registry:

npm config set registry http://registry.npmjs.org/

Then install your package with npm install node-sass

For me these things didn't work and I had the same issue but I was able to solve it through another app that had the binary for node-sass in the vendor folder so I sudo mv the folder to my other project and it was able to run it ok. I know it might not be a good solution but that was something that I tried that worked.

Answer 4

Workaround, that makes this works:

Go to the folder

username/.npm/node-sass // on linux
username/AppData/Roaming/npm-cache/node-sass //on windows

inside create directory /4.9.2

From this page https://github.com/sass/node-sass-binaries get specific version and put this file inside 4.9.2 folder. Now try run npm installation - should work!

Answer 5

try this command:

sudo npm install --save-dev  --unsafe-perm node-sass

Answer 6

The best way to get rid of permission issues is by installing npm/node using brew.

1. Uninstall npm (How do I completely uninstall Node.js, and reinstall from beginning (Mac OS X))
2. Install brew /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
3. Install node/npm by using the following command brew install node

Answer 7

sudo npm install -g --unsafe-perm node-sass

This must fix the problem

Answer 8

Permission problem to your directory '/Users/matt/node_modules/node-sass/build' kindly right click on Users/matt and go to properties uncheck ReadOnly then on the same window move to security check fro every user whether the full control is given for the folder else change it to full-control for Everyone
