解决方法：

#首先先添加清华的镜像源conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/conda config --set show_channel_urls yes#如果无法解决，则删除channels配置文件中部分内容#具体操作如下:#1、快速创建channels配置文件的备份(保险起见)cp ~/.condarc{,.bak}#查看配置文件的内容cat ~/.condarc.bak channels:  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/  - https://nanomirrors.tuna.tsinghua.edu.cn/anaconda/cloud  - defaults  - https://nanomirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda  - https://nanomirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/conda  - bioconda  - r  - conda-forgeshow_channel_urls: true#2、删除部分内容#修改后配置文件的内容如下：vim ~/.condarcchannels:  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/show_channel_urls: true
