          }
        }
      }
    }
  }
}

当我使用 ng lint 命令时出现以下错误:

node:internal/process/promises:246
          triggerUncaughtException(err, true /* fromPromise */);
          ^

[UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason "#<Object>".] {
  code: 'ERR_UNHANDLED_REJECTION'
}

我测试卸载一些包，没有变化!

有同样的问题。在我的例子中，tsconfig.json 中有尾随逗号。如何获取错误堆栈跟踪:

1. 使用节点 v16.15+
2. 再次运行 ng lint 以查看完整的堆栈跟踪，以查看错误

在我的例子中，这是属性缺失错误，因为 compilerOptions 中最后一个选项后有不必要的逗号，配置阅读器认为逗号后应该是另一个具有值的属性。
