错误描述



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.


是在创建conda新环境的时候出现的: conda create -n myEnvironmentName python=3.7

PS:如果是安装依赖包不使用pip install, conda安装博不太友好..

问题解决：

(这个方法对我有效，不知道对你有没有效)

1. 终端打开conda配置文件gedit .condarc

2.删除原文件内容并替换为下面的:



1 channels:
 2   - defaults
 3 show_channel_urls: true
 4 default_channels:
 5   - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
 6   - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free
 7   - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r
 8 custom_channels:
 9   conda-forge: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
10   msys2: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
11   bioconda: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
12   menpo: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
13   pytorch: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
14   simpleitk: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
