WebPack：无效的配置对象。已使用与API模式不匹配的配置对象初始化了Webpack

Question

WebpackOptionsValidationError：无效的配置对象。已使用与API架构不匹配的配置对象初始化了Webpack。

我正在使用Angular 6项目：

运行ng test --code-coverage时遇到错误。但是在运行ng test和ng serve和ng build时，它工作正常。我试图找到解决此问题的方法。

但我无法解决此问题。您能解决这个问题吗？

详细错误：

ng test --code-coverage
WebpackOptionsValidationError: Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
 - configuration.module.rules[14].include should be one of these:
   RegExp | string | function | [(recursive)] | object { and?, exclude?, include?, not?, or?, test? } | [RegExp | string | function | [(recursive)] | object { and?, exclude?, include?, not?, or?, test? }]
   -> One or multiple rule conditions
   Details:
    * configuration.module.rules[14].include should be an instance of RegExp
    * configuration.module.rules[14].include: The provided value "" is not an absolute path!
    * configuration.module.rules[14].include should be an instance of function
    * configuration.module.rules[14].include should be an array:
      [RegExp | string | function | [(recursive)] | object { and?, exclude?, include?, not?, or?, test? }]
    * configuration.module.rules[14].include should be an object.

您的命令应为

ng test --code-coverage=true

如果您想在每次运行测试套件时创建代码覆盖率报告，则可以在CLI配置文件angular.json中设置以下选项：

"test":{ 
  "options":{   
  "codeCoverage": true 
  }
}

通过查看错误的方式进行更新

configuration.module.rules[14].include: The provided value "" is not an absolute path!

尝试查看具有路径的任何配置
