Error: Path variable [contenthash:8] not implemented in this context: static/css/[name].[contenthash:8].css

A temporary solution that you can use until it’s fixed, is to replace [contenthash] with something like [md5:contenthash:hex:20].

一時的な解決策がこれみたい


/Users/hogehoge/workspace/example/web/config/webpack.config.prod.js


// Note: defined here because it will be used more than once.
- const cssFilename = 'static/css/[name].[contenthash:8].css';
+ const cssFilename = 'static/css/[name].[md5:contenthash:hex:20].css';

  • 参考URL:https://koukitips.net/post1967/
  • yarn add [email protected]"extract-text-webpack-plugin": "^4.0.0-beta.0",をインストールする。
  • extract-text-webpack-pluginはwebpack4に対応しないからmini-css-extract-pluginを使うようにしたほうがいいとかあるけど、4.0.0-beta.0をインストールしたら解決した。
