考虑创建一个单独的环境，例如，
conda create --name foo -c conda-forge axelrod
base 环境是 conda 包所在的环境，它应该在那里占据主导地位。也就是说，人们永远不需要为了其他任何事情而降级它。一般来说，我建议用户不要使用base环境进行工作。
我通过以下命令在我的 miniconda 中安装新模块
conda install -c conda-forge axelrod
它试图解决但说我没有正确的 conda 版本。

考虑创建一个单独的环境，例如，
conda create --name foo -c conda-forge axelrod
base 环境是 conda 包所在的环境，它应该在那里占据主导地位。也就是说，人们永远不需要为了其他任何事情而降级它。一般来说，我建议用户不要使用base环境进行工作。
