我有一个问题与terser-webpack-plugin我不能缩小我的捆绑错误是

来自Terser的Data.js中出错Data.js无效赋值

我有“terser-webpack-plugin”的版本：“4.2.3”，“webpack”：“^4.33.0”，“clean-webpack-plugin”：“^3.0.0”，“dotenv-webpack”：“^1.7.0”和React 17.0.0

这里你可以看到我的webpack配置

const HtmlWebpackPlugin = require('html-webpack-plugin');
const Dotenv = require('dotenv-webpack');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const { EnvironmentPlugin, ProgressPlugin } = require('webpack');
const TsconfigPathsPlugin = require('tsconfig-paths-webpack-plugin');
const modeConfig = (env, target) => require(`./build-utils/webpack.${env}`)(target);
const presetConfig = require('./build-utils/loadPresets');
const targetUtils = require('./build-utils/targetUtils');
module.exports = ({ mode, presets, target } = { mode: 'production', presets: [] }) => {
    return webpackMerge(
        {
            mode, // minify the code in production mode
            entry: './src/index.tsx',
            output: {
                path: path.join(__dirname, 'dist'),
                filename: 'bundle.js',
            },
            module: {
                rules: [
                    {
                        test: /\.tsx?$/,
                        loader: 'awesome-typescript-loader',
                        options: {
                            configFileName: 'tsconfig.build.json',
                        },
                    },
                ],
            },
            resolve: {
                extensions: ['.ts', '.tsx', '.json', '.js'],
                plugins: [new TsconfigPathsPlugin()],
            },
            plugins: [
                new CleanWebpackPlugin(),
                new Dotenv({ path: targetUtils.getEnvFile(target), systemvars: true }),
                new ProgressPlugin(),
                new HtmlWebpackPlugin({
                    template: path.resolve(rootDir, 'index.html'),
                    mode,
                }),
                new EnvironmentPlugin(process.env),
            ],
            externals: targetUtils.getExternals(target),
            node: {
                fs: 'empty',
            },
        },
        modeConfig(mode, target),
        presetConfig({ mode, presets }),
    );
};
