1.初始未显示，jupyter打开界面显示

2.查询发现是安装在虚拟环境导致的问题

3.遂卸载，安装在base中，再次报错

pkg_resources.ContextualVersionConflict: (jupyter-core 4.6.3 (d:\anaconda\anaconda\lib\site-packages), Requirement.parse('jupyter-core>=4.7'), {'nbconvert'})

4.更新jupyter-core 5.5.0

pip install jupyter-core --ignore-installed jupyter-core

5.再次尝试安装后报错 

pkg_resources.ContextualVersionConflict: (jupyter-client 6.1.6 (d:\anaconda\anaconda\lib\site-packages), Requirement.parse('jupyter-client>=6.1.12'), {'nbclient'}) 

6.尝试升级 jupyter-client失败

pip install jupyter-client -- upgrade

ERROR: Could not find a version that satisfies the requirement upgrade (from versions: none)
ERROR: No matching distribution found for upgrade

7.走投无路下咨询了大老师成功安装8.6.0 

pip install --upgrade jupyter-client 

8.再次尝试安装成功
