【问题描述】：

我刚刚从 anaconda.com 安装了 Anaconda。安装进行得很顺利。之后，我试图从这个 environment.yml 文件创建一个新环境。 (nbdev.yml)

我试过conda env create -f nbdev.yml 但它只是卡在解决环境问题上。然后我了解到mamba 是 conda 的快速替代品。 所以我输入了mamba env create -f nbdev.yml 和 .

【参考方案1】：

经过大量研究，我偶然发现了Mamba doesn't find a solution when mixing conda forge defaults and not specifying Python explicitly 1102。所以我只是从

编辑了 nbdev.yml

name: nbdev
channels:
  - fastai
  - defaults
  - conda-forge
dependencies:
  - _r-mutex
  - _tflow_select
  - absl-py
  - alabaster

到

name: nbdev
channels:
  - fastai
  - defaults
  - conda-forge
dependencies:
  - python
  - _r-mutex
  - _tflow_select
  - absl-py
  - alabaster

这解决了问题。
