appdynamics(node.js/express)依赖性与webpack折断 - 任何人确认

Question

是否有人在使用AppDynamics库时会经历过WebPack依赖关系编译问题？您是否找到了一种解决方法的方法？我相信这是来自他们的图书馆的问题。

尝试安装用于监视node.js/express应用程序的AppDynamics软件包时，我们的WebPack构建过程无法导入少数依赖关系。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用法在我们的服务器文件的顶部AS：

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

和我们的WebPack配置是：

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，将节点环境降低到10.15，并为AppDynamics软件包使用其他导入方法，但这似乎是AppDynamics Library内部的问题吗？主要问题是，使用AppDynamics库时是否有人经历了WebPack依赖关系编译问题？您是否找到了一种解决方法的方法？

任何帮助或线索都将不胜感激❤️

解决方案在WebPack配置中将" AppDynamics"添加到"外部"：https：//webpack.js.org/configuration/configuration/externals/

这允许appdynamics使用默认node.js需要导入。
