其实在清华源anaconda里写了全部的步骤，也可以看原版https://mirror.tuna.tsinghua.edu/help/anaconda

具体步骤
第一步，打开cmd

第二步：cmd中执行

conda config --set show_channel_urls yes

第三步：进入C:\Users\Administrator（这里的Administrator可以是你的用户名）

第四步：记事本方式打开.condarc文件

第五步：将文件内容修改为以下(原文件最好备份一个）

channels:
  - defaults
show_channel_urls: true
channel_alias: https://mirrors.tuna.tsinghua.edu/anaconda
default_channels:
  - https://mirrors.tuna.tsinghua.edu/anaconda/pkgs/main
  - https://mirrors.tuna.tsinghua.edu/anaconda/pkgs/free
  - https://mirrors.tuna.tsinghua.edu/anaconda/pkgs/r
  - https://mirrors.tuna.tsinghua.edu/anaconda/pkgs/pro
  - https://mirrors.tuna.tsinghua.edu/anaconda/pkgs/msys2
custom_channels:
  conda-forge: https://mirrors.tuna.tsinghua.edu/anaconda/cloud
  msys2: https://mirrors.tuna.tsinghua.edu/anaconda/cloud
  bioconda: https://mirrors.tuna.tsinghua.edu/anaconda/cloud
