I was working on webpack 4.44.2, I face this error when I convert to webpack5.0.0
ERROR in ./src/assets/sass/styles.scss Module build failed (from ./node_modules/mini-css-extract-plugin/dist/loader.js): Error: Automatic publicPath is not supported in this browser at E:\maktab\Control-panel\newcontrol\final-control\node_modules\css-loader\dist\cjs.js!
the error is from the font file bath in fonts.scss
@font-face {
font-family: "Janna LT";
src: local("Janna LT"), url(../fonts/janna.woff) format("woff");
font-weight: normal;
}
@font-face {
font-family: "Janna LT";
src: local("Janna LT"), url(../fonts/janna-bold.woff) format("woff");

console.log("hellow from webpack5");The suggested solutions didn't work for me. However, I found that setting publicPath to an empty string did the trick.
output: {
publicPath: '',
...
}
I encountered the same issue. My code compiles into the dist-folder without any further structure. The following code works for me and is simple since I need an empty path.
'module': {
rules: [
{
test: /\.css$/,
use: [
{
loader: MiniCssExtractPlugin.loader,
options: {
publicPath: ''
}
},
{
loader: "css-loader"
}
]
}
]
}
You can go crazy and do things like that, too:
{
loader: MiniCssExtractPlugin.loader,
options: {
publicPath: (resourcePath, context) => {
return path.relative(path.dirname(resourcePath), context) + '/';
},
},
},
Details you can find here: https://webpack.js.org/plugins/mini-css-extract-plugin/#the-publicpath-option-as-function
The error is caused by a bug in mini-css-extract-plugin 1.3.8 and lower in combination with Webpack 5. It is triggered when a stylesheet references a resource using url(...) and the publicPath option is not set explicitly in the Webpack configuration.
I took the time to reproduce and report the issue here: https://github.com/webpack-contrib/mini-css-extract-plugin/issues/707
Yesterday, version 1.3.9 has been released and it includes the fix for this issue. You should be able to resolve this error by upgrading.
