The node sass download here failed. I used cnpm instead. I’m afraid that the download commands in the future will be unstable. In the future, I used cnpm instead of NPM for downloading. The command is
npm install -g cnpm --registry=https://registry.npm.taobao.org
If you don’t understand anything or other solutions, please leave a message at the message office. I hope you can like it!
The command to change to cnpm is
cnpm install pug sass-loader node-sass --save-dev
