CondaHTTPError: HTTP 000 CONNECTION FAILED for url ＜https://repo.anaconda.com/pkgs/main/osx-64

问题

使用命令 conda search python ，出现错误：CondaHTTPError: HTTP 000 CONNECTION FAILED for url https://repo.anaconda.com/pkgs/main/osx-64/repodata.json

% conda search python
Loading channels: failed

CondaHTTPError: HTTP 000 CONNECTION FAILED for url

'https://repo.anaconda.com/pkgs/main/osx-64'

原因

输入命令：conda info，看到现有的channels

 - https://repo.anaconda.com/pkgs/main/osx-64
  - https://repo.anaconda.com/pkgs/main/noarch
  - https://repo.anaconda.com/pkgs/r/osx-64
  - https://repo.anaconda.com/pkgs/r/noarch

因为国外的网络很难连上，可以修改为国内的网络，比如清华源。

解决

打开 .condarc 文件：open .condarc，看到以下内容：

show_channel_urls: true
ssl_verify: false

修改为：

channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/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/pkgs/main/
show_channel_urls: true
ssl_verify: false
