Laravel 使用 NPM 遇到的问题

执行npm run dev
然后终端显示
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! @ development: NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the @ development script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
