Chunk.entrypoints: Verwenden Sie stattdessen Chunks.groupsIterable und filtern Sie nach der Instanz von Entrypoint

Beim Versuch, meine App zu starten, werden folgende Fehler angezeigt ...

npm install extract-text-webpack-plugin@next

Das hat den Trick für mich getan!

Die meisten Kommentare hier https://github.com/webpack-contrib/extract-text-webpack-plugin/issues/701 weisen darauf hin extract-text-plugin, sie mini-css-extract-pluginstattdessen zu ändern .

Aus dem Github-Repo von extract-text-webpack-plugin https://github.com/webpack-contrib/extract-text-webpack-plugin

⚠️ Seit Webpack v4 sollte das Extract-Text-Webpack-Plugin nicht für CSS verwendet werden. Verwenden Sie stattdessen das Mini-CSS-Extrakt-Plugin.

Gehen Sie zu mini-css-extract-plugin, wie man swap / upgraden https://github.com/webpack-contrib/mini-css-extract-plugin

Ja, ich habe das gleiche Problem mit dem Webpack 4.10.2. Das Problem ist behoben, nachdem ich das getauscht extract-css-chunks-webpack-pluginhabe mini-css-extract-plugin.

Hier sind die Änderungen an der Webpack-Konfiguration:

-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........
     //
   ]

Hoffe es kann helfen.

Ich hatte den Fehler mit der Version 4.0.0-beta.0von behoben extract-text-webpack-plugin.
