之前配置清华镜像如下：
[root@localhost bin]# conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
[root@localhost bin]# conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
[root@localhost bin]# conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
[root@localhost bin]# conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/
[root@localhost bin]# conda config --set show_channel_urls yes
[root@localhost bin]# conda config --get channels
后来修改.condarc文件（vi /root/.condarc），删除所有镜像，只添加这两个镜像。
[root@localhost ~]# cat /root/.condarc
channels:
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/
show_channel_urls: true
