使用 copy-webpack-plugin 后构建失败。webpack 和插件版本已经过兼容性测试（webpack5 cwp10） 我已经没有想法了 :( 有没有人遇到过熟悉的东西？这可能是跨模块兼容性问题吗？

进一步提供错误日志和配置代码 提前致谢

错误是

我使用 copy-webpack-plugin 10.2.0 和 webpack 5.65.0。我想将public/js文件夹中的js文件复制到dist/js.

plugins: [
    new CopyWebpackPlugin({
        patterns:[
            {
                from:'public/js/*.js',
                to:path.resolve(__dirname, 'dist','js'),
            
            }
        ]
    })
],

但是设置也将路径复制到dist中，它变成了dist/js/public/js。我尝试添加flatten:true但有错误

Invalid options object. Copy Plugin has been initialized using an options object that does not match the API schema.
 - options.patterns[0] has an unknown property 'flatten'. These properties are valid:
   object { from, to?, context?, globOptions?, filter?, transformAll?, toType?, force?, priority?, info?, transform?, noErrorOnMissing? }

那要怎么做呢？

使用 Webpack 和 copy-webpack-plugin 我需要在构建过程中复制整个文件夹，我有：

plugins: [
  new CopyPlugin({
    patterns: [
      { from: './src/assets', to: './assets' }
    ]
  })
]

但是，当assets文件夹为空时，这会失败：

ERROR: unable to locate ...

如果我将一个文件添加到资产文件夹，我将工作。

如何解决这个问题？

我copy-webpack-plugin从升级4.6.0到6.0.2

我改变了我的代码

plugins: [
    new CopyWebpackPlugin([{
      from: clientAssetPath,
      to: paths.STATICS,
      ignore: [ '.gitkeep' ],
    }], {
      debug: 'info'
    }),
    new HtmlWebpackPlugin({
      ...htmlPluginOptions,
    }),
    new DynamicCDNWebpackPlugin({
      resolver: unpkgResolver,
    }),
  ]

到

plugins: [
    new CopyPlugin([{
      patterns: [{
        from: clientAssetPath,
        to: paths.STATICS,
        noErrorOnMissing: true
      }]
    }]),
    new HtmlWebpackPlugin({
      ...htmlPluginOptions,
    }),
    new DynamicCDNWebpackPlugin({
      resolver: unpkgResolver,
    }),
  ]

如官方网站所示

但它开始抛出以下错误： compilation.getLogger is not a function

当我调试它时，我发现错误来自 node_modules/copy-webpack-plugin/dist/index.js 不知道是什么问题

在一个 electron.js 应用程序中，我试图根据这些指示从 node.js 调用和执行 python 脚本：https : //nodejs.org/api/child_process.html#child_process_child_process_execfile_file_args_options_callback

import { execFile } from 'child_process';

let pythonPath = '/home/marco/anaconda3/bin/python3';

execFile('./scripts/factorial.py',
  [parseInt(msg)],
  { cwd: './scripts',
    env: '/home/marco/anaconda3/bin/python3'
  },
  (error, stdout, stderr) => {
    if (error) {
      throw error;
    }
    console.log(stdout);
  }
);

我得到这个错误：

评论options部分时：

execFile('./scripts/factorial.py',
  [parseInt(msg)],
  //{ cwd: './scripts',
    //env: '/home/marco/anaconda3/bin/python3'
  //},
  (error, stdout, stderr) => {
    if (error) {
      throw error;
    }
    console.log(stdout);
  }
);

我犯了同样的错误。

按照此处找到的指示：https : //www.tutorialspoint.com/run-python-script-from-node-js-using-child-process-spawn-method 我修改了代码如下：

const { spawn } = require('child_process'); …
