node.js - 使用Webpack编译的AppDynamics(Node.js/Express)依赖关系已损坏-有人可以确认吗？

使用AppDynamics库时，有人遇到过Webpack依赖项编译问题吗？您是否找到解决该问题的方法？我相信这是源于他们的图书馆的问题。

尝试安装AppDynamics软件包以监视Node.js / Express应用程序时，我们的Webpack构建过程无法导入少数依赖项。具体来说，错误输出为：

我们的项目设置为：
-Webpack v4.29.0
-Node.js v11.0.0
-Appdynamics v4.5

Appdynamics用法位于我们服务器文件的顶部，如下所示：

// AppDynamics monitoring
require("appdynamics").profile({
  controllerHostName: ***
  controllerPort: 443,
  controllerSslEnabled: true,
  accountName: ****
  accountAccessKey: ***
  applicationName: ***
  tierName: ***
  nodeName: '01'
 });

我们的Webpack配置为：

const path = require('path');
const webpack = require('webpack');

module.exports = {
  entry: { server: './server.ts' },
  resolve: { extensions: ['.js', '.ts'] },
  target: 'node',
  // TO-DO: Enable "production" mode for going live with Universal
  mode: 'development',
  // this makes sure we include node_modules and other 3rd party libraries
  externals: [/node_modules/],
  output: {
    path: path.join(__dirname, 'dist'),
    filename: '[name].js'
  },
  module: {
    rules: [{ test: /\.ts$/, loader: 'ts-loader' }]
  },
  plugins: [
  ]
};

到目前为止，我们已经尝试将Webpack版本降级，将Node环境降级到10.15，并对AppDynamics包使用其他导入方法，但这似乎是Appdynamics库内部的问题？主要问题是，使用Appdynamics库时，是否有人遇到过Webpack依赖项编译问题？您是否找到解决该问题的方法？

任何帮助或线索将不胜感激❤️

最佳答案

解决方案是在Webpack配置的“外部”中添加“ appdynamics”：https://webpack.js.org/configuration/externals/

这允许AppDynamics使用默认的Node.js需要导入。
