TestCafe-错误[ERR_HTTP_HEADERS_SENT]：将标头发送到客户端后无法设置标头

Question

开始使用TestCafe在随机位置获得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，该模块是createTestCafe() api上的包装器。该模块称为testcafe-runner，并像"testcafe-runner": "file:local_modules/testcafe-runner"这样安装。

我开始收到以下异常错误：

所有测试javascript文件都位于C：\ MyTests文件夹中。

在本地模块和项目上安装的testcafe 1.8.4版本
