conda 创建新环境报错问题解决
Collecting package metadata (current_repodata.json): failed CondaHTTPError: HTTP 000 CONNECTION FAILED for url https://repo.anaconda.com/pkgs/main/win-64/current_repodata.json
1，先切换国内的镜像
2，切换后依旧报错，可能是http和https的问题，将channels更改为如下情况则可以解决
channels: - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/ - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/ - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/ - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
