Cloning root environment with Anaconda
提问by birone
Going through one of (very few available) tutorials on Anaconda, I tried:
通过关于 Anaconda的（非常少的）教程之一，我尝试了：
$ conda create -n rootclone --clone root
This failed:
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:
https://github.com/conda/conda/issues
Include the output of the command 'conda info' in your report.
Traceback (most recent call last):

MemoryError
And badly. The environment is created:
而且很糟糕。创建环境：
$ 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
But it's not working at all:
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
But is this a true bug, or is conda create -n --clonejust not designed for cloning the conda root environment?
但这是一个真正的错误，还是conda create -n --clone不是为克隆 conda 根环境而设计的？

The MemoryErrorindicates that the conda process ran out of memory. Perhaps you need to allocate more swap memory.
该MemoryError指示畅达进程耗尽内存不足。也许您需要分配更多的交换内存。

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
使用以下命令克隆Anaconda默认的root环境，root环境命名为base。这对我有用 Anaconda3-5.0.1
conda create --name <env_name> --clone base
