解决思路
导入错误：无法从“pip.\u internal.exceptions”（E:\ProgramData\Anaconda3\lib\site packages\pip\\u internal\exceptions.py）导入名称“invalidSchemeComposition”
解决方法
pip命令出现了问题，解决方法有两个
T1、重新安装pip

第一步，定位到pip命令所在的程序文件路径，删除该文件夹下的pip相关的文件夹
第二步，使用conda强制删除环境中pip
conda remove --force pip
第三步，使用conda重新安装pip
conda install -c anaconda pip
T2、改为conda下载对应的包
conda install pyserial
