这个错误通常发生在使用Angular CLI创建项目时，原因是Webpack版本太低。可以通过在项目中手动升级Webpack版本来解决这个问题。

具体方法如下：

1. 在项目目录下，打开package.json文件，找到"webpack"依赖项。

2. 将其升级为最新版本，例如："webpack": "^4.41.6"。

3. 在终端中运行npm install命令，以安装最新版本的Webpack。

4. 运行ng serve命令重新启动应用程序，错误应该已经消失了。

示例：

在package.json文件中，将原先的"webpack": "^3.6.0"改为"webpack": "^4.41.6"：
