Collecting package metadata (current_repodata.json): failed
 
UnavailableInvalidChannel: The channel is not accessible or is invalid.
  channel name: https//mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main

You will need to adjust your conda configuration to proceed.
Use `conda config --show channels` to view your configuration's current state,
and use `conda config --show-sources` to view config file locations.

解决方法：

首先用conda config --show channels命令看一下都有什么镜像，

conda config --show channels

输出为：

channels:
  - https//mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
  - defaults

然后使用conda config --remove-key channels命令恢复默认配置，这时就只剩下

最后在进行conda create配置环境就可以啦，如果想要新的镜像，自己再添加想要的镜像就可以了
