Chunk.entrypoints: utilisez Chunks.groupsIterable et filtrez par instance de Entrypoint à la place

Je vois les erreurs suivantes lorsque j'essaye de démarrer mon application ...

npm install extract-text-webpack-plugin@next

Cela a fait l'affaire pour moi!

La plupart des commentaires ici https://github.com/webpack-contrib/extract-text-webpack-plugin/issues/701 pointent à le extract-text-pluginchanger à la mini-css-extract-pluginplace.

Depuis le dépôt Github de extract-text-webpack-plugin https://github.com/webpack-contrib/extract-text-webpack-plugin

⚠️ Depuis webpack v4, le plugin extract-text-webpack-plugin ne doit pas être utilisé pour les css. Utilisez plutôt mini-css-extract-plugin.

Rendez-vous mini-css-extract-pluginsur la façon de l'échanger / de le mettre à niveau https://github.com/webpack-contrib/mini-css-extract-plugin

Oui, j'ai eu le même problème avec Webpack 4.10.2. Le problème est résolu après que je l'échangerais extract-css-chunks-webpack-pluginà mini-css-extract-plugin.

Voici les changements de configuration du webpack:

-const ExtractCssChunks = require('extract-css-chunks-webpack-plugin')
+const MiniCssExtractPlugin = require("mini-css-extract-plugin");

module.exports = {
  name: 'client',
  target: 'web',
  module: {
    rules: [
      {
        test: /\.css$/,
-       use: ExtractCssChunks.extract({
-         use: 'css-loader'
-       })
+       use: [
+         {
+           loader: MiniCssExtractPlugin.loader,
+         },
+         "css-loader"
+       ]
      }
    ]
  },
// 
// other config........
//
   plugins: [
-    new ExtractCssChunks(),
+    new MiniCssExtractPlugin({
+        filename: `components/[name].css`
+    }),
     //
     // other config........
     //
   ]

J'espère que cela peut vous aider.

J'avais corrigé le bogue en utilisant la version 4.0.0-beta.0de extract-text-webpack-plugin.
