Cucumber 错误：该"；从「；参数的类型必须为字符串。接收未定义

我正在使用WebDrivero v7（最新稳定版本）和cucumber。
我得到一个错误：

error:“from”参数必须是string类型。接收到未定义的

这是堆栈跟踪：

这是我的package.json依赖项：

有人知道哪里出了问题吗？

谢谢

我通过删除

“cucumber”：“^6.0.5”

依赖项并在

package.json

文件中使用

“@cucucumber/cucucumber”：“^7.1.0”

解决了这个问题。
在我的steps文件中，我导入了如下语句：

import {Then, When} from '@cucumber/cucumber';    

与此相反：

import {Then, When} from 'cucumber';  

这似乎是WebDrivero v7与cucumber整合的新方式。（如中所述）

import {Then, When} from 'cucumber';
