问题描述：

使用conda create --name xxx python=xxx在conda的(base)环境下创建新环境时，出现这样的报错。在其它conda环境中使用conda install xxx安装包时也出现这样的报错。好像所有的conda语句都不能执行了

问题解决：

1.退出到(base)环境中

conda deactivate

2.使用以下语句查看.condarc文件位置

conda config --show-sources

3.如果得到类似于这样的结果，就记录.condarc文件位置并删除这个文件：

==> /root/.condarc <==
channels:
  - https://anaconda.org
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/
  - defaults

show_channel_urls: True

rm /root/.condarc

 之后再执行在非(base)环境软件包或在(base)环境创建新环境都能正常执行了
