CondaHTTPError: HTTP 000 CONNECTION FAILED for url

前言

想运行一下这个开源项目https://github.com/viluiz/gan的代码，安装依赖时执行下面这句话：

conda env create -f environment.yml

然后报错

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/win-64/repodata.json>

在浏览器输入上面网址提示：Too many files to list

一、查看配置

首先打开cmd命令查看自己的conda的通道配置。

conda config --show

custom_channels:
  anaconda/pkgs/main: https://mirrors.tuna.tsinghua.edu.cn
  anaconda/pkgs/r: https://mirrors.tuna.tsinghua.edu.cn
  anaconda/pkgs/msys2: https://mirrors.tuna.tsinghua.edu.cn
  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
  pytorch-lts: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  simpleitk: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
custom_multichannels:
  defaults:
    - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
    - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r
    - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2

二、解决办法

1、通过cmd修改

通过下面的cmd命令可以直接修改添加源（此办法我没有验证我用到下面的方法）

conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
conda config --set show_channel_urls yes

2、通过.condarc文件进行更改

在C:\Users\xxxx下找到文件.condarc：将https全部换成http即可

channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
  - defaults
show_channel_urls: true
default_channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r
  - 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
  pytorch-lts: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  simpleitk: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud

1、特别注意，如果.condarc文件找不到的话，是因为没有在cmd命令中输入 conda config命令，只有第一次输入该命令之后，系统才会自动创建.condarc文件。（.condarc指的是运行期配置文件）
2、如果原本的源中的源地址是 https，可以直接改成http即可。这个方法可以特别注意，因为https有时候会出现连接错误的问题，改成http后不会再出现此类问题。

三、新的问题

上面的问题解决了，安装了几分钟后又出现下面问题

conda env create -f environment.yml

Collecting package metadata (repodata.json): done
Solving environment: done
Preparing transaction: done
Verifying transaction: done
Executing transaction: done
ERROR conda.core.link:_execute(699): An error occurred while installing package 'conda-forge::qt-5.12.9-h5909a2a_4'.

    known_paths = addsitepackages(known_paths)

    addsitedir(sitedir, known_paths)

    addpackage(sitedir, name, known_paths)

    for n, line in enumerate(f):

    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc4 in position 18: invalid continuation byte
return code: 1
()

看报错信息location of failed script: C:\Users\25212\anaconda3\envs\py3ml\Scripts.qt-post-link.bat 好像是目录C:\Users\25212\anaconda3\envs\py3ml\Scripts\下找不到qt-post-link.bat 这个文件，在anaconda3文件夹下搜索到了一个这个文件放了进去，然后继续执行

conda env create -f environment.yml 
结果显示
CondaValueError: prefix already exists: C:\Users\25212\anaconda3\envs\py3ml

应该是之前创建过同名的虚拟环境但是并没有成功创建完成导致的。

1、解决问题

1、查看conda环境信息

conda info

            shell level : 0
       user config file : C:\Users\25212\.condarc

                          C:\Users\25212\AppData\Local\conda\conda\envs

             netrc file : None
           offline mode : False

2、打开目录C:\Users\25212\anaconda3\envs\删掉py3ml文件夹即可，继续执行依然老样子，看https://github.com/ContinuumIO/anaconda-issues/issues/10949这个链接下有个解决办法是找到以下文件：“C:\Users\25212\anaconda3\pkgs\qt-5.12.9-h5909a2a_4\Scripts.qt-post-link.bat”，在文件的 @echo off这一行下面加上这句：

set PATH=%PATH%;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;

再尝试安装就可以了；于是加了这句话（分号也带着），然后又报错了：

把添加的那句话的分号去掉；还是没解决。。。后面又试了更新conda

conda install conda --update-all

还是没用

又试了清理然后重新安装

conda clean --all

还是没用。。目前还未解决，先记录在这

20220311，又试了几个方法，把路径C:\Users\xxx\anaconda3\Library\bin下面的libcrypto-1_1-x64.dll和libssl-1_1-x64.dll复制到路径anaconda3\Dlls下；然后更新conda

conda update -n base conda
conda update --all

也没用完全解决，但好像能多往下走几个done。。
