首先安装jupyter 的前提是需要提前安装python 3.3版本及以上。然后输入 pip install jupyter,出现下面问题
python -V //在命令行窗口输入，验证python的版本
pip install jupyter
最后出现
[notice] A new release of pip available: 22.3.1 -> 23.0.1
[notice] To update, run: python.exe -m pip install --upgrade pip说明pip版本过低，输入 python.exe -m pip install --upgrade pip.
C:\Users\唐文杰>python.exe -m pip install --upgrade pip
Looking in indexes: http://mirrors.aliyun.com/pypi/simple/
Requirement already satisfied: pip in d:\python.last\lib\site-packages (22.3.1)

通过查找资料(32条消息) 已解决（pip报错）WARNING: The repository located at mirrors .aliyun.com is not a trusted or secure host and_袁袁袁袁满的博客-CSDN博客，发现需要设置信任的镜像地址
在pip命令后面加上--trusted-host mirrors.aliyun.com，
pip install jupyter -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com
最后只是解决了pip在安装第三方包的时候，在 pip install 第三方包 后面加 新的镜像源地址，再加--trusted-host mirrors.aliyun.com，文章来源：https://www.toymoban.com/news/detail-613617.html
