      _config.yml of themea: c: 'bar'

    Completely drops cheerio [#3850], [#3677]

    • This means Hexo no longer includes cheerio as part of its production dependencies (it's still a development dependency)

      const cheerio = require('./node_modules/hexo/node_modules/cheerio/index')const cheerio = require('./node_modules/cheerio/index')

    • To use cheerio,

      $ npm install --save cheerio

      const cheerio = require('cheerio')
