Question

As title. I've maintained a project that web page is developed using Angular.js and some utilities, but something wrong when I use the "npm install" command, and the error log was shown below....

But I didn't met the same erroe when I build another project that using Angular 12. Is it matters or do I missed something that I can't build without it? Could someone guide me to solve it?

Answer 1

I had this problem too,
what I did :
1- npm uninstall node-sass
2- npm i -D sass
3- npm i

Answer 2

This usually happens because your environment has changed since running npm install. Run npm rebuild node-sass to download the binding for your current environment."
So I ran npm rebuild node-sass and that worked! Then npm install and everything went ok.

Answer 3

node-sass require limited Node Version, you need check the node's version is which node-sass compatible.
