1、错误描述
最近使用conda create环境时遇见下面错误，Ubuntu和Windows都会遇到：
Collecting package metadata (current_repodata.json): failed
CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/main/linux-64/current_repodata.json>
Elapsed: -
An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.
If your current network has https://www.anaconda.com blocked, please file
a support request with your network engineering team.
'https://repo.anaconda.com/pkgs/main/linux-64'
2、解决方法
（1）首先检查防火墙是否关闭
这是很坑的，我折腾了好久发现防火墙没关闭！！！
（2）推荐修改镜像源
Windowns直接搜索.condarc进行编辑，Ubuntu则使用下面命令编辑：
vi ~/.condarc
直接把下面内容复制粘贴：
channels:
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/Paddle/
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/fastai/
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/
show_channel_urls: true
ssl_verify: false
但是windows下有时候还是有问题，尝试将https改为http就没问题了。
（3）不行了换个网络或者换手机热点试试哈哈哈
