Thank, i already solve this. I was missing node-gyp. Solved this with

npm install --global --production windows-build-tools
npm install -g node-gyp

[fsmaili77]

Under Ubuntu 20.04, I have solved the problem by modifying the file package.json (the dependency: “node-sass”: “xx.xx.x” by “sass”: “^1.49.0”. As explained by @fabiocanon After this I have executed the following commands:

sudo apt-get update sudo apt-get install build-essential

And finally with npm start I have succeded to launch the project.
