问题

使用python部署独立环境小伙伴因为网速慢没少吃苦。下面的异常你一定见过，或者似曾相识

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/linux-64/qt-5.12.5-hd8c4c69_1.tar.bz2>

我就想好好的安装环境，干嘛让我吃闭门羹。

解决方法

Anaconda下载速度很慢，笔者换了Miniconda速度稍微好一些。但是一些资源minconda还是下载不到。经过最终寻找，笔者在清华大学镜像网站上找到设置中国镜像源的版本如下：

#1、备份本地配置 
cp ~/.condarc ~/.condarc.bak

vim ~/.condarc
#2、删除原来的内容，填入以下
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



#3、清除缓存
conda clean -i

结果

再次安装依赖包即成功，日志如下
