在运行构建时出现的错误：

here my error at run build:

    /MovieDB/node_modules/jest-worker/build/WorkerPool.js:25
      } catch {
              ^

    SyntaxError: Unexpected token {

此处是我的webpack.common.js：

here my webpack.common.js:

const path = require('path');
const webpack = require('webpack');
const HtmlPackPlugin = require('html-webpack-plugin');
const terserPlugin = require('terser-webpack-plugin');

module.exports = {
  entry: './src/index.js',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'bundle.js'
  },
  module: {
    rules: [
      {
        test: /\.css$/,
        use: ['style-loader', 'css-loader']
      }
    ]
  },
  plugins: [
  new HtmlPackPlugin({
    template: './src/index.html',
    filename: 'index.html'})
  ],
  optimization: {
    minimize: true,
    minimizer: [
      new terserPlugin({
        test: /\.js(\?.*)?$/i,
      })
    ],
    sourceMap: true
  }
}

此处我的webpack.dev.js

here my webpack.dev.js

const merge = require('webpack-merge');
const common = require('./webpack.common.js');

module.exports = merge(common, {
    mode: "development",
    devtool: 'inline-source-map'
})

推荐答案

您使用的是哪个Node.js版本？

what's the version of Node.js are you using?

我在运行最新的3.0.2版本的terser-webpack-plugin时遇到了相同的错误。根据发布日志，3.0.0中引入了一些重大更改，其中之一是最低支持的Node.js版本是10.13

I ran into the same error when I was running the latest terser-webpack-plugin @ 3.0.2. According to the release log, there were some breaking changes introduced in 3.0.0 and one of them was "minimum supported Node.js version is 10.13"

将terser-webpack-plugin降级到2.3.6。

It worked when I downgraded terser-webpack-plugin to 2.3.6.

因此，如果您使用的版本早于10.13，则可能必须升级Node.js或降级terser-webpack-plugin。

So you'll probably have to upgrade your Node.js if you're using a version earlier than 10.13, or downgrade your terser-webpack-plugin.
