错误如下

Error: ERROR processing skip func of /home/dylan/hh-fcc/hardhat-smartcontract-lottery-fcc/deploy/00-deploy-mocks.js:
TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider')

我沿着freecodecamp教程，我做了两次。我以为我可能打错了什么。但还是不行。我重新创建了目录，所以我假设它不是一个安装/依赖问题，但我是一个新手，所以谁知道呢。我搜索并尝试了围绕这个错误的一些提示，但我找不到解决方案。我迷路了，请帮助，我将上传我的js文件下面。请要求更多，如果你认为他们会有帮助。
