Question

作为一个干净的节点项目，我做了：

npm install webpack copy-webpack-plugin

这是我的webpack.config.js文件：

var CopyWebpackPlugin = require('copy-webpack-plugin');
var path = require('path');

module.exports = {
  plugins: [
    new CopyWebpackPlugin([
      {
        from: 'src',
        to: 'dist'
      }
    ])
  ]
};

当我运行npm run webpack时收到此错误消息：

$ npm run webpack

> test@1.0.0 webpack /var/www/html/test
> webpack

/var/www/html/test/node_modules/webpack/bin/convert-argv.js:507
                throw new Error("'output.filename' is required, either in config file or as --output-filename");
                ^

    at startup (bootstrap_node.js:187:16)

周围没有具体的解决方案。怎么解决呢？

尝试在webpack.config.js

中添加entry和output

const CopyWebpackPlugin = require('copy-webpack-plugin');
const path = require('path');

const rootPath = path.join(__dirname, '/');

module.exports = {
  entry: {
    main: `${rootPath}/src/main.js`,
  },

  output: {
    filename: '[name].[hash].js',
    path: `${rootPath}/dist`,
  },

  plugins: [
    new CopyWebpackPlugin([
      {
        from: 'src',
        to: 'dist'
      }
    ])
  ]
};

希望这可以帮助你。

webpack copy plugin给出错误：输出文件名是必需的，可以是配置文件，也可以是--output-filename
