在Visual Studio代码中调试Cucumber-nightwatch代码时遇到错误

Question

我正在使用带有黄瓜的守夜表，它非常适合我，但是当我开始执行调试部分时，我陷入了错误，无法找出解决方法。

错误描述如下，运行launch.json后，我可以看到VS代码的调试控制台

Debugger listening on [::]:46131
There was an error while starting the test runner:

Error: Cannot read source folder: {directory path}/examples/tests

at /Users/{directory path}/node_modules/nightwatch/lib/runner/run.js:203:21 
at {directory path}/node_modules/nightwatch/lib/runner/walk.js:97:18   
at FSReqWrap.oncomplete (fs.js:123:15)

下面是我的launch.json文件

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Launch Program",
            "program": "${workspaceFolder}/node_modules/nightwatch/bin/nightwatch"
        }
    ]
}

作为参考，我已从url下面进行了操作
