【问题描述】：

我正在尝试打包一个电子应用程序，但我收到了这个错误：

ValidationError: Invalid options object. Copy Plugin has been initialized using an options object that does not match the API schema.
 - options[0] misses the property 'patterns'. Should be:
   [non-empty string | object  from, to?, context?, globOptions?, toType?, force?, flatten?, transform?, cacheTransform?, transformPath?, noErrorOnMissing? , ...] (should not have fewer than 1 item)

在.electron-vue\webpack.renderer.config.js，我有：

new CopyWebpackPlugin([
  
    from: path.join(__dirname, '../static'),
    to: path.join(__dirname, '../dist/electron/static'),
    ignore: ['.*']
  
]),

将其更改为以下，并不能解决错误：

    new CopyWebpackPlugin(

      patterns: [
         from: path.join(__dirname, '../static'), to: path.join(__dirname, '../dist/electron/static') ,
      ],

    ),

我不确定新模式应该是什么。我查看了this question 并尝试遵循该模式，但没有奏效。我怎样才能解决这个问题？

【参考方案1】：

我必须在 .electron-vue\webpack.web.config.js 中更改相同的内容

/**
 * Adjust webConfig for production settings
 */
if (process.env.NODE_ENV === 'production') 
  webConfig.devtool = ''

  webConfig.plugins.push(
    new MinifyPlugin(),
    new CopyWebpackPlugin(
      //this is the new change
      patterns: [
         from: path.join(__dirname, '../static'), to: path.join(__dirname, '../dist/electron/static') ,
      ],

    ),
    new webpack.DefinePlugin(
      'process.env.NODE_ENV': '"production"'
    ),
    new webpack.LoaderOptionsPlugin(
      minimize: true
    )
  )
