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，并以"testcafe-runner": "file:local_modules/testcafe-runner"的形式安装。

除了以下例外，我开始收到错误消息：

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。
