使用 Anaconda 克隆根环境

2022-01-10 00:00:00 python clone anaconda

问题描述

浏览了其中一个(非常少的)Anaconda 教程，我尝试了:

Going through one of (very few available) tutorials on Anaconda, I tried: 

$ conda create -n rootclone --clone root

这失败了:

src_prefix: '/home/bir/conda'
dst_prefix: '/home/bir/conda/envs/rootclone'
Packages: 49
Files: 471
An unexpected error has occurred, please consider sending the
following traceback to the conda GitHub issue tracker at:

Include the output of the command 'conda info' in your report.

而且很糟糕.环境已创建:

And badly. The environment is created:

$ conda info -e
# conda environments:
#
oracle                   /home/bir/conda/envs/oracle
oracleclone              /home/bir/conda/envs/oracleclone
rootclone                /home/bir/conda/envs/rootclone
root                  *  /home/bir/conda

但它根本不起作用:

$ . activate rootclone
discarding /home/bir/conda/bin from PATH
prepending /home/bir/conda/envs/rootclone/bin to PATH
(rootclone)bir@N2C:~/python$ which python
/usr/bin/python   # Should be in /home/bir/conda/envs/rootclone/bin

但这是一个真正的错误，还是 conda create -n --clone 只是不是为克隆 conda 根环境而设计的?

But is this a true bug, or is conda create -n --clone just not designed for cloning the conda root environment?

解决方案

使用如下命令克隆Anaconda默认的根环境，根环境命名为base.这对我有用 Anaconda3-5.0.1

Use following command to clone default root environment of Anaconda, the root environment is named as base. This worked for me with Anaconda3-5.0.1

conda create --name <env_name> --clone base
