使用conda恢复python版本

我安装了最新版本的 Anaconda,其中包括 python=3.8。然后我意识到我需要 python=3.6(因为 gurobi=9.0.2)!正如 documentation 所暗示的(见第二个要点),我只是做了

conda install python=3.6

然而,这花了很多时间,我遇到了几次冲突!虽然从一开始对我来说很有意义!旧版本的 python 如何与新版本附带的所有软件包一起使用? 我知道我可以简单地用 python=3.6 创建一个新环境!但我想改变我的(基础)!

我错过了什么吗?这显然是文档所建议的(注意:由于 Stackoverflow 的限制,我删除了一些日志)!
