Anaconda创建新的虚拟环境报错

    之前也用anaconda创建过新的虚拟环境，使用的是清华的镜像源，但是从这次再进行创建的时候报错了，在网上搜了好久都没有解决，决定记录一下我的步骤。
    首先看看我们的报错是否一样吧

我使用 conda create -n NAME python=3.7 这句命令

这时候可以查看一下这个路径 C:\Users\Administrator下的.condarc文件，如果有-default 就把那行删除再重新试一下但是我还是报错了

所以我更换了镜像源，把.condarc文件内容直接改掉
这是原来清华的：

这是改过的：
channels:

• https://mirrors.ustc.edu.cn/anaconda/pkgs/free/

show_channel_urls: true

    然后保存，关掉，重新打开anaconda prompt输入conda create -n NAME python=3.7就好啦
