TestCafe -错误[ERR_HTTP_HEADERS_SENT]：无法在将标头发送到客户端之后设置标头

Question

开始使用TestCafe在随机位置获取Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client。

我有一个本地节点模块，它是createTestCafe()应用编程接口上的包装器。模块名为testcafe-runner，安装方式如下："testcafe-runner": "file:local_modules/testcafe-runner"。

我开始收到错误，但出现了以下异常：

Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client

所有测试javascript文件都位于C:\MyTests文件夹中。

在local_module和项目上都安装了TestCafe1.8.4版本
