我该如何解决这个问题？

Answer 1

PermissionError: [Errno 13] Permission denied: 'C:\\Users\\felixkim1023\\AppData\\Roaming\\jupyter\\runtime\\kernel-0a76fc02-0376-4747-a88f-0effa941a976.json'

这句话很清楚，您没有权限。如果您使用的是bash shell，请确保使用sudo运行命令，即：

sudo jupyter notebook

如果您不是（例如，您在Windows Powershell中），请确保以管理员身份启动Shell（右键单击以管理员身份启动）。
