conde提示CondaHTTPError: HTTP 000 CONNECTION FAILED for url ＜https:mirrors.tuna.tsinghua.edu.cn

1.背景说明

新接手的项目，使用miniconda运行，于是按照miniconda官方文档进行安装。因为默认镜像比较慢，所以使用清华大学的镜像，并按照官网的配置。

conda清华镜像源：Anaconda 镜像使用帮助

步骤1：

# 在用户家目录创建conda配置文件 vim ~/.condarc # 粘贴官网的参考配置 channels: - defaults show_channel_urls: true channel_alias: https://mirrors.tuna.tsinghua.edu.cn/anaconda default_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/pkgs/r - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/pro - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2 custom_channels: conda-forge: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud msys2: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud bioconda: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud menpo: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud pytorch: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud simpleitk: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud # 清空本地conda索引缓存 conda clean -i

步骤2：创建新虚拟环境时，会提示报错

(base) niefajun@ubuntu:~$ conda create -n test_env Collecting package metadata (current_repodata.json): done Solving environment: done CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r/noarch/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. 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r/noarch'

从提示信息，大概可以知道，是因为连接清华镜像源获取环境配置json信息的过程中，出现连接失败。

2.问题解决

修改问题的方法很简单，就是把官方的参考配置文件做一个简单的修改

channels: - defaults show_channel_urls: true channel_alias: https://mirrors.tuna.tsinghua.edu.cn/anaconda default_channels: - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/pro - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2 custom_channels: conda-forge: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud msys2: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud bioconda: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud menpo: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud pytorch: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud simpleitk: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud

把每一个https形式链接地址，修改成http形式就可以

再次测试：

(base) niefajun@ubuntu:~$ conda create -n test3_env Collecting package metadata (current_repodata.json): done Solving environment: done ==> WARNING: A newer version of conda exists. <== current version: 4.8.2 latest version: 4.9.0 Please update conda by running $ conda update -n base -c defaults conda ## Package Plan ## environment location: /home/niefajun/miniconda3/envs/test3_env Proceed ([y]/n)? y Preparing transaction: done Verifying transaction: done Executing transaction: done # # To activate this environment, use # # $ conda activate test3_env # # To deactivate an active environment, use # # $ conda deactivate (base) niefajun@ubuntu:~$
