conda create environment 命令给出 'Found conflicts! Looking for incompatible packages.'

Question

我通过 choco install miniconda3 安装了 miniconda。

创建 python3 环境效果很好。

conda create --name envA python=3 --verbose

但是创建python2环境有问题。

conda create --name envB python=2 --verbose

Collecting package metadata (current_repodata.json): ...working... done
Solving environment: ...working... failed with repodata from current_repodata.json, will retry with next repodata source.

切换到曼巴舞提供了更好的诊断。

mamba create -n foo python=2

Looking for: ['python=2']

conda-forge/win-64                                          Using cache
conda-forge/noarch                                          Using cache
Encountered problems while solving:
 - nothing provides vc 9.* needed by python-2.7.12-0

然后用mamba找vc.

mamba search vc

# Name                       Version           Build  Channel
vc                              14.1      h21ff451_1  conda-forge
vc                              14.1      h6d1b3ff_2  conda-forge
...

vc v9可以在defaults频道找到。

mamba search 'vc[channel=defaults]'

# Name                       Version           Build  Channel
vc                                 9      h2eaa2aa_6  pkgs/main
...

用 defaults 频道更新 .condarc，解决了问题。

channels:
  - conda-forge
  - defaults
channel_priority: disabled

最后一点，如果其他人发现自己处于这种情况...

作为安装 mambaforge.

的一部分，~/.condarc 已更改（删除 defaults 频道）
