解决方案：
打开.condarc文件在（C:\Users\用户名）如下：

channels:
  - https://mirrors.ustc.edu.cn/anaconda/pkgs/main/
  - https://mirrors.ustc.edu.cn/anaconda/pkgs/free/
  - https://mirrors.ustc.edu.cn/anaconda/cloud/conda-forge/
ssl_verify: true

删除 - https://mirrors.ustc.edu.cn/anaconda/cloud/conda-forge/
再次新建环境，成功。
