Initially I got the same error while I wanted to install the css-loader using npm i --save-dev css-loader, then i followed these links npm WARN registry Unexpected warning for https://registry.npmjs.org/:
to sort out problem
// when i run the npm i command for installing the below package
// It is the package.json file
{
"name": "HelloReact",
"version": "1.0.0",
"scripts": {
"build": "webpack",
"dev": "webpack-dev-server"
},
