npm install extract-text-webpack-plugin@next
This did the trick for me!
Most of the comments here https://github.com/webpack-contrib/extract-text-webpack-plugin/issues/701
point to extract-text-plugin change it to mini-css-extract-plugin instead.
From the Github repo of extract-text-webpack-plugin https://github.com/webpack-contrib/extract-text-webpack-plugin
⚠️ Since webpack v4 the extract-text-webpack-plugin should not be used for css. Use mini-css-extract-plugin instead.
Head over to
mini-css-extract-plugin on how to swap/upgrade it
https://github.com/webpack-contrib/mini-css-extract-plugin
Yea, I got the same issue with webpack 4.10.2. The problem is fixed after I swap the extract-css-chunks-webpack-plugin to mini-css-extract-plugin.
Here's the webpack config changes:
-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........
//
]
Hope it can help.
