使用gulp压缩静态博客资源

npm install --global gulp-cli #全局安装gulp指令集
npm install gulp --save #安装gulp插件

npm install gulp-htmlclean --save-dev
npm install gulp-html-minifier-terser --save-dev
# 用gulp-html-minifier-terser可以压缩HTML中的ES6语法

npm install gulp-clean-css --save-dev
# 压缩css

npm install gulp-terser --save-dev
# 压缩js

npm install gulp-fontmin --save-dev
# 压缩字体包
