开发期间无法通过Webpack4访问％PUBLIC_URL％/ favicon.ico

Question

我的webpack.config.js和package.json如下所示。当我进行构建时，/dist目录中确实包含favicon.ico。但是，进行npm run start会产生URIError: Failed to decode param '/%PUBLIC_URL%/favicon.ico'。

目录结构为

#webpack.config.js

const HtmlWebPackPlugin = require("html-webpack-plugin");
const CopyWebpackPlugin = require('copy-webpack-plugin')

const htmlWebpackPlugin = new HtmlWebPackPlugin({
    template: "./public/index.html",
    filename: "./index.html"
});
const copyWebpackPlugin = new CopyWebpackPlugin([{
    from: './public/favicon.ico',
    to: './favicon.ico'
}]);

module.exports = {
    module: {
        rules: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                use: { loader: "babel-loader" }
            },
            {
                test: /\.css$/,
                use: [ { loader: "style-loader" }, { loader: "css-loader" } ]
            },
            {
                test: /\.(pdf|jpg|png|gif|svg|ico)$/,
                use: [ { loader: 'url-loader' } ]
            }
        ]
    },
    plugins: [htmlWebpackPlugin, copyWebpackPlugin]
};
