离线环境conda虚拟环境备份迁移--conda pack问题

1.第一步：创建虚拟环境

conda create -n pyenv --clone base 
或者
conda create -n pyenv python==3.8.5 --offline

命令执行结束，在路径/xxxx/anaconda/envs 下看到pyenv
或者 conda info --envs 查看罗列虚拟环境

2.第二步：打包环境

conda pack -n pyenv -o /xxxxx/pyenv.tar.gz

报错：
Collecting packages...
CondaPackError: 
Files managed by conda were found to have been deleted/overwritten in the
following packages:

- python='3.8.5'

This is usually due to `pip` uninstalling or clobbering conda managed files,
resulting in an inconsistent environment. Please check your environment for
conda/pip conflicts using `conda list`, and fix the environment by ensuring
only one version of each package is installed (conda preferred).

网上搜一圈，没有能解决问题的，最后得重装虚拟环境，费时费力

我的办法：
直接把/xxxx/anaconda/envs 下的pyenv打包压缩即可zip -r  pyenv.zip /xxxx/anaconda/envs/pyenv

3.第三步：激活环境

将pyenv.zip 拷贝到另外一个系统上并解压到目录下/xxxx/anaconda/envs/

unzip -d /xxxx/anaconda/envs/  pyenv.zip

然后激活环境 source activate /xxxx/anaconda/envs/pyenv

亲测在linux 64 系统上可用！！
