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

参考文章：https://stackoverflow.com/questions/67446140/importerror-cannot-import-name-invalidschemecombination-from-pip-internal-ehttps://stackoverflow.com/questions/67446140/importerror-cannot-import-name-invalidschemecombination-from-pip-internal-e

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

哈哈，大功告成！
