Question

我在node.js和express.js中有我的项目。我需要制作一个node.js项目的可执行文件。

项目配置：

使用ES6功能：导入和动态导入，为此，我正在使用babel.js。

项目状态：

项目正常运行没问题。

该项目的移植正在进行中。捆绑创建就可以了。

问题/错误/问题：

使用命令打包时：

pkg。 -调试

给出“导入”错误

package.json配置：

{
  "name": "server",
  "version": "0.0.0",
  "private": true,
  "bin": "./app.js",
  "main":"./app.js",
  "engines": {

      "views/**/*",
      "public/*"
    ],
    "targets": [
      "node8"
    ]
  }
}

webapck.config.js：

module.exports = {
   node: {
    __dirname: true,
    __filename: true
 },
 target: 'node',
  mode: 'development', 
  entry: ["./app.js"],
  output: {
    filename: '[name].bundle.js',
    path: path.resolve(__dirname, 'output')    
  },
  module: {
    rules: [
      {
        test: /\.css$/,
        use: [
          'style-loader',
          'css-loader'
        ]
      },
      {
        test: /\.m?js$/,
        exclude: /(node_modules|bower_components)/,
        resolve: {
            extensions: [".js",".json"]
        },
        use: [{
            loader: 'babel-loader',
            options: {
                presets: [
                    '@babel/preset-env'                   
                 ],
                 plugins: [
                    '@babel/plugin-transform-runtime'
                 ]
            }
        }]
      }
    ],
    exprContextRegExp: /$^/,
    exprContextCritical: false
  }
};

我得到的错误：

原因是什么？

有人可以提出一些建议或策略吗？

Answer 1

pkg .将使用bin的{{1}}属性，并使用该属性来确定条目文件，在您的情况下为package.json。

假设该文件没有被转译，并且您想打包已转译的捆绑软件，请尝试以下操作：

app.js

如何使节点项目可执行？
