修改.condarc文件:

对于linux该文件在用户根目录下,即~/.condarc,windows系统则在C:\Users\用户名）下,修改改文件,去掉-defaults的那行,然后保存!
检查一下是否能够下载了?
不管是否能下载,最好都替换一下镜像源,并且有时候也可能是因为镜像源的问题,下载太慢

修改镜像源:

在命令行中依次执行下命令:

    conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/

    conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/

    conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

    conda config --set show_channel_urls yes

接下来应该就ok了
如果还不行，那就删除 conda-forge，删除后环境就能配置了。conda-forge是为了建立和维护软件包而发起的，有的包必须从这里面下，但是不一定把它写到配置里面也能用。
注意镜像源不是越多越好！
