1 背景

唐老哥帮我安装了Stream包，然而虚拟环境命名为py-monocle（就是python环境下类似monocle包功能的包），担心过几天就忘了着什么东西，所以准备改个名。但是conda是不支持虚拟环境的重命名的，因此需要通过复制和删除原环境的方法更名。

2 通过复制和删除操作“重命名”conda虚拟环境

首先进行复制，报了一大堆error，不过没关系：

conda create --name py-stream --clone py-monocle
Source:      /mnt/d/Linux/software/anaconda/envs/py-monocle
Destination: /mnt/d/Linux/software/anaconda/envs/py-stream
Packages: 428

>>> quit()

stream包是可以成功导入的。
然后删除原来的环境：
