webpack3 upgrade webpack4
VUE-cli -g install npm
VUE project name and the init webpack has been the default
cd project name
npm run dev (normal interface to indicate success) to view the version number of webpack package.json, the version upgrade is 3 to 4 npm install after you'll find webpack @ ^ 4 -D run after an error, so we have to be handled according to error contents, because webpack upgrade, that webpack-dev-server also need to upgrade to the latest npm install webpack-dev-server @ latest -D run error, suggesting you webpack-cli not installed cnpm install webpack-cli @ latest -D run newspaper html-webpack-plugin wrong cnpm install html-webpack-plugin @ latest -D run eslint-loader error cnpm install eslint-loader @ latest report -D run newspaper vue-loader error
CNPM install vue-loader @ Latest -D
CNPM install CSS-Loader @ Latest -D
CNPM install postcss @ Latest -D-Loader
