在使用conda创建新环境时，出现问题如下：

Collecting package metadata (current_repodata.json): failed

在网上搜索了各种解决办法：

1.更换镜像源。在系统文件中找到.condarc文件（一般隐藏在C:\Users\ASUS，点击查看-隐藏的项目）。在网上搜索并进行内容更换，如https改为http、删除conda-forge、更换镜像源等。

2.使用conda clean -i 清除缓存。

3.检查网络连接，甚至看了文章准备重新安装anaconda。，conda报错：Collecting package metadata (current_repodata.json): failed - 知乎 (zhihu.com)https://zhuanlan.zhihu.com/p/673594875

反正就是一直的报错，弄了一天整的人都蔫了，菜鸟反复撞墙。。。

因为上面一直显示的 requests.exceptions.HTTPError: 404 Client Error: Not Found for url: http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/noarch/current_repodata.json以及 requests.exceptions.HTTPError: 429 Client Error: Too Many Requests for url: http://mirrors.ustc.edu.cn/anaconda/pkgs/free/win-64/current_repodata.json，所以问题还是在镜像源上。

开始查找最新镜像源，发现有人说很多镜像源不能用了，点开了清华大学镜像站，使用当中的

对.condarc文件进行更新，终于终于解决了问题！
