conda在创建ipykernel时无法克隆环境

Question

I'd like to avoid installing every individual package in a new environment with the following command in anaconda3:

conda create -n py3 ipykernel --clone root

but I get this error:

TooManyArgumentsError: Too many arguments: did not expect any arguments for --clone. Got 1 argument (ipykernel) and expected 0.

First cloning the environment and then installing ipykernel also doesn't work:

~>conda create -n py3 --clone root
[...]
~>source activate py3
(py3) ~>conda install ipykernel
Fetching package metadata .......
Solving package specifications: ..........


InstallError: Install error: Error: one or more of the packages already installed depend on 'conda'
and should only be installed in the root environment: conda-env
These packages need to be removed before conda can proceed.

My end goal is to have a couple envs I can launch in jupyter notebook. I'd like to avoid having to reinstall every package for every env in the case that the python version is the same as [root] env. Having just downloaded the full anaconda distribution, I find myself rebuilding it piecemeal into the environment. I'm wondering if there is a better way to do this.

Conda itself can only be installed in root. Just follow the instructions. Inside your new environment, uninstall conda-env :

(py3) ~> conda unistall conda-env

Now, try to install again:

(py3) ~>conda install ipykernel
