Angular Cli-语法错误：'；导入&x27；和'；出口'；只能与'；sourceType:module'；

我正在尝试使用angular cli生成覆盖率报告。然而，我不断得到以下错误。我不太确定这是cli错误还是Karma.conf的问题<代码>ng测试/

npm测试

运行良好。。。那么这和代码覆盖率选项有关吗

今天我遇到了同样的问题，我的案例中的修复是对tsconfig.spec.json文件的更改。我将模块条目从“模块”更改为“es2015” 至

“模块”：“commonjs”

---

这解决了运行

ng test--cc

时出现的编译错误，并创建了预期的覆盖率报告。希望这有帮助
