Question

使用AppDynamics库时，有人遇到过Webpack依赖项编译问题吗？您找到了解决该问题的方法吗？我相信这是源于其库的问题。

当尝试安装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，为：

我们的Webpack配置为：

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

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？您找到了解决该问题的方法吗？

任何帮助或线索都会受到赞赏❤️

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

这允许AppDynamics使用默认的Node.js需要导入。

使用Webpack编译的AppDynamics（Node.js / Express）依赖关系破裂-有人可以确认吗？
