【问题描述】：
我正在尝试将 favicon 添加到我使用 webpack 制作的基于 React 的网站。添加网站图标是一场彻头彻尾的噩梦，我尝试了许多解决方案都无济于事。向我推荐的最新解决方案称为“favicons-webpack-plugin”，可在此处找到：https://github.com/jantimon/favicons-webpack-plugin。
如果有人能告诉我我做错了什么，我们将不胜感激。
运行“npm run start”时出现以下错误
这是我的目录结构：
这是我的 webpack.config.js 文件：
const path = require('path');
const merge = require('webpack-merge');
const webpack = require('webpack');

这是我的 server.js 文件：
/* Global Requires */
const express = require('express');
const logger = require('morgan');
const bodyParser = require('body-parser');
const path = require('path');
const app = express();
const ReactDOM = require('react-dom')
var favicon = require('serve-favicon');
if(process.env.NODE_ENV === 'development') {
console.log('in development.');
require('dotenv').config();
} else {
console.log('in production.');
}
/* App Config */
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
app.use(express.static(path.join(__dirname, 'build')));
app.use(favicon(__dirname + '/public/favicon.ico'));
app.use(logger('dev'));
/* Server Initialization */
app.get('/', (req, res) => res.sendFile('index.html'));
var port = process.env.PORT || 3000;
app.listen(port, () => console.log(`Server initialized on // ${new Date()}`));

只要确保它至少为 16x16... 并且网站图标因浏览器而异 - 有些不会显示，除非它完全是 16x16，有些是 32x32，哦，使用 png 而不是 jpg..
-
你的问题是 webpack 没有捆绑你的 ico 文件吗？还是页面没有显示它。您可以使用
file-loader让 wepack 将文件加载到您的包中，然后在您的 html 页面中调用它。 -
嘿@CodeYogi，如果我的解决方案对你有用，你想把它标记为正确答案吗？
