【问题描述】：
我正在将我们 Web 应用程序中的库更新到最新版本，从而将 Webpack 升级到 Webpack5。在调整“webpack.config.dev.js”的参数时，我在编译过程中不断遇到以下错误：
...../node_modules/webpack/lib/NormalModule.js:1306
hash.update(this.buildInfo.hash);
^
TypeError: Cannot read property 'hash' of undefined
到目前为止，这是我的 webpack.config.dev.js 文件（我删除了 cmets 以尝试让它更短一点）：
'use strict';
const autoprefixer = require('autoprefixer');
const path = require('path');
const webpack = require('webpack');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const CaseSensitivePathsPlugin = require('case-sensitive-paths-webpack-plugin');
const InterpolateHtmlPlugin = require('react-dev-utils/InterpolateHtmlPlugin');
const WatchMissingNodeModulesPlugin = require('react-dev-utils/WatchMissingNodeModulesPlugin');
const eslintFormatter = require('react-dev-utils/eslintFormatter');
const ModuleScopePlugin = require('react-dev-utils/ModuleScopePlugin');
const getClientEnvironment = require('./env');
const paths = require('./paths');
const publicPath = 'http://localhost:3000/';
const publicUrl = 'http://localhost:3000/';
const env = getClientEnvironment(publicUrl);
const BundleTracker = require('webpack-bundle-tracker');
// This is the development configuration.

module.exports = {

};
这是我当前的相关库（或者至少是我认为相关的库，如果需要，我肯定会发布其他库）
html-webpack-plugin@5.3.2
webpack@5.51.1
react-dev-utils@11.0.4
我认为导致问题的部分是插件，特别是 HtmlWebpackPlugin：
plugins: [
*** I think the HtmlWebpackPlugin is causing the issue ***
new InterpolateHtmlPlugin(HtmlWebpackPlugin, env.raw),
// Generates an `index.html` file with the <script> injected.
new HtmlWebpackPlugin({
// inject: true,
template: paths.appHtml,
hash: false,
}),
...
],
关于如何修复错误的任何想法？我觉得我正确调用了 HtmlWebpackPlugin，但我是不是很笨？
更新 1： 反转 InterpolateHtmlPlugin 和 HtmlWebpackPlugin 会产生相同的错误
更新 2： HtmlWebpackPlugin 被确定不是问题的原因，此时错误正在追溯到 Webpack。
更新 3： 重新创建错误的 Git 存储库位于：https://github.com/mexicantexan/webpack-error-reproduction 并在以下链接中打开了一个问题：https://github.com/webpack/webpack/issues/14142
更新 4： 已解决。检查下面的选中标记的解决方案。
【问题讨论】：
-
你能在插件数组上反转
HtmlWebpackPlugin和InterpolateHtmlPlugin吗？HtmlWebpackPlugin是第一个，或者你有什么特定的原因 -
是的，没有理由，这只是别人在我之前写的哈哈。如果我反转它，我会收到相同的错误消息：``` node_modules/webpack/lib/NormalModule.js:1306 hash.update(this.buildInfo.hash); ^ 类型错误：无法读取 NormalModule.updateHash 中未定义的属性“哈希”```
