QGIS安装开源python插件报错，如何解决？

因为是github上的开源插件，根据描述已经适配了QGIS3.16
我使用的操作系统是win10，所以我将代码下载后复制到了插件所在的目录下，QGIS可以识别到插件的存在，但是还有一些问题

项目地址如下：https://github.com/sbraden/circle-craters

选择安装插件后，及出现以下错误

无法加载插件“circle-craters”因在调用其classFactory()方法时发生错误

ModuleNotFoundError: No module named 'CircleCraters'

考虑是python的问题，针对性的做了一些参数调整，但是并未成功解决

结果就是希望能够成功安装
