ubuntu16.04 conda创建虚拟环境报错CondaHTTPError: HTTP 000 CONNECTION FAILED解决办法

报错与分析

问题： 发送命令conda create -n py37 python=3.7报错如下：

Collecting package metadata (current_repodata.json): failed

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

If your current network has https://www.anaconda.com blocked, please file
a support request with your network engineering team.

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

解决步骤：

1. 更换清华源（仍然不成功）

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --set show_channel_urls yes

2. 删除~/.condarc中内容，并更新成下方内容

auto_activate_base: false
channels:
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/
  - defaults
show_channel_urls: true
ssl_verify: false
report_errors: false

3. 重点： 新开一个terminal，若有虚拟环境退出虚拟环境，再执行conda create -n py37 python=3.7 （测试成功）
