Mac M1芯片无法安装Python3.7的conda环境

用conda安装python3.7的环境，出现错误

(base) ➜  CodeAnalysis git:(main) ✗ conda create -n CodeAnalysis3.7 python=3.7
Collecting package metadata (current_repodata.json): done
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.
Collecting package metadata (repodata.json): done
Solving environment: failed

PackagesNotFoundError: The following packages are not available from current channels:

  - python=3.7

　　

解决方法：

在Apple Silicon系统上使用3.7的直接替代方法是使用Rosetta模拟x86_64，详情见这篇文章。

## 创建一个空的环境
conda create -n py37

## 启动该环境
conda activate py37

## 使用x86_64 architecture channel(s)
conda config --env --set subdir osx-64

## 安装python3.7之类的操作 install python, numpy, etc. (add more packages here...)
conda install python=3.7
