  • Check the output property in the webpack.config.js - DiDex
  • @DiDex seems to be all normal there: jsfiddle - Yaroslav Kurov
  • @DiDex, where is the output if this optional property + error crashes due to webpack-cli? - overthesanity
  • @YaroslavKurov, you are using an outdated version of webpack-cli , with the release of webpack> = 4 - released and cli 3 versions, upgrade the package - overthesanity
  • @overthesanity yes, it helped, thanks. - Yaroslav Kurov
