实际上 spyder-kernels已经是 2.0.1
这个错误提示目前可以不理它,待 spyder下个版本修复它.
见:https://stackoverflow.com/questions/66952832/spyder-5-missing-dependencies-spyder-kernels-version-error
(Spyder maintainer here) That error message is caused by a bug in Spyder and it’ll be fixed in our next version (5.0.1), to be released shortly.
You can safely ignore it for now because it incorrectly reports that the right version of spyder-kernels is missing, when it’s actually installed.
