I’m getting the following error:

npm ERR! Make sure you have the latest version of node.js and npm installed.

I solved by commenting out the following lines in the webpack.config.js file:
// const ImageminPlugin = require('imagemin-webpack-plugin').default;
// new ImageminPlugin({
// optipng: {
// optimizationLevel: 7,
// },
// gifsicle: {
// optimizationLevel: 3,
// },
// pngquant: {
// quality: '65-90',
// speed: 4,
// },
// svgo: {
// removeUnknownsAndDefaults: false,
// cleanupIDs: false,
// },
// jpegtran: null,
// plugins: [imageminMozjpeg({
// quality: 75,
// })],
// disable: (config.enabled.watcher),
// }),
Upgrading imagemin-webpack-plugin
to version 1.2.0
DOES NOT fix this error.
