npm为html
嘿所以我是webpack的新手，我正在尝试将它用于使用Cesium js api的项目。我在线跟随他们的教程到T但由于某种原因，当我运行命令“npm run build”时，如果没有正确执行，我会收到以下错误。

我在我的webpack.config.js文件中有这个：
const path = require('path');
const webpack = require('webpack');
const HtmlWebpackPlugin = require('html-webpack-plugin');
module.exports = {
context: __dirname,
entry: {
app: './src/index.js'
},
output: {
filename: '[name].js',
path: path.resolve(__dirname, 'dist'),
},
module: {
rules: [{
test: /\.css$/,
use: [ 'style-loader', 'css-loader' ]
}, {
test: /\.(png|gif|jpg|jpeg|svg|xml|json)$/,
use: [ 'url-loader' ]
}]
},
plugins: [
new HtmlWebpackPlugin({
template: 'src/index.html'
})
]
};
我在package.json中添加了以下脚本行
"scripts": {
"build": "node_modules/.bin/webpack --config webpack.config.js"
}
我不确定我做错了什么..我试着看看警告是否是问题，但似乎不是这样。我假设它的功能导致错误，但我该如何解决？非常感谢！
回答如下：Webpack 4有一些弃用更改，html-webpack-plugin的作者没有更改新需求的代码，这就是为什么这个插件不适用于新的webpack 4版本。
核心webpack团队分叉了这个插件，直到作者更改了初始代码和他们的包可用这个包contrib/html-webpack-plugin
所以你应该安装这个fork而不是原来的。
您可以通过简单地从npm或纱线安装来实现
npm i -D html-webpack-plugin@webpack-contrib/html-webpack-plugin
或用纱线
yarn add -D html-webpack-plugin@webpack-contrib/html-webpack-plugin
没有要求使用完全纱线=）您也可以通过npm进行
