首先是可以从报错内容看到提示指定的python版本，由于是新电脑，压根还没装python，所以先去官网下载了一下

然后文件报错:

ModuleNotFoundError: No module named ‘protobot’ 意思应该是没有protobot这个python包

然后我在下载的文件夹里的电机驱动函数库找到了protobot这个文件夹,然后把它放到了webots工程里，

在readme文件里看到安装它的方式

然后我问chatgpt，它列出的原因里有一条说可能是代理的原因，然后我把梯子关了，报错少了很多:

继续问chatgpt，回答说

先是pip install –upgrade setuptools，然后还是报错，然后使用清华大学镜像，pip install setuptools -i https://pypi.tuna.tsinghua.edu.cn/simple，然后就Ok了。接着就继续前面的cd src , pip install -e .就可以正常安装这个protobot包了，中间电脑不要熄屏，以免下载中断报错，得重新再下载。

这样，这个webots工程就正常跑起来了，这次问题的原因主要还是自己对python环境的不熟悉，安装python包都不知道怎么装。
