Whenever I run my code I always get the same error. I uninstall node and npm and reinstall. But now there is no "node_modules" and I get the same error. How can I fix it?

There isn't node-sass and node-gyp. When I tried to install them I also got the same error. I cannot install anything.

npm vue.js node.js python javascript

I solved this problem by changing the node version to 14.15.1

Please don't waste your time running the suggested command by others. Please uninstall node.js and use the Node v14.x. It will solve it automatically.

I got the same error and did this:

 1. npm install node-sass
 2. npm install  
 3. npm ci
 4. ng serve --open (to launch the project ).
