npm测试“笑话”给出TypeError，但笑话有效

问题描述

我正在尝试使用Jest（我第一次使用Jest）对React Native项目进行测试，并且每当我运行npm test时都会遇到此错误。

> @ test D:\repo\foldername
> jest

path.js:39
    throw new ERR_INVALID_ARG_TYPE('path','string',path);
    ^

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type object

我尝试在没有jest的情况下呼叫npm test，并且运行正常。这是我拥有的package.json：

    "start": "expo start","android": "expo start --android","ios": "expo start --ios","web": "expo start --web","eject": "expo eject","test": "jest"

    ]
