anaconda创建新环境问题

问题描述

• 实验环境：Windows10；Anaconda3

安装完anaconda后使用命令 conda create -n test3.7 python=3.7 准备新建一个虚拟环境，出现错误，具体如下所示：

C:\Users\dell>conda create -n test3.7 python=3.7
WARNING: The conda.compat module is deprecated and will be removed in a future release.
Collecting package metadata: failed

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/main/win-64/repodata.json.bz2>
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.

SSLError(MaxRetryError('HTTPSConnectionPool(host=\'repo.anaconda.com\', port=443): Max retries exceeded with url: /pkgs/main/win-64/repodata.json.bz2 (Caused by SSLError("Can\'t connect to HTTPS URL because the SSL module is not available."))'))

分析问题

看错误说的大概是：链接网络出现错误。上网搜索给的建议基本都是更换源，如：

问题：输入conda upgrade --all显示错误CondaHTTPError: HTTP 000 CONNECTION FAILED for url
解决：直截了当——查询.condarc文件，把内容改为如下所示内容，使用清华大学镜像。
原因：Anaconda Navigator主服务器访问困难

笔者试了一下，未能解决问题。

问题解决

因为我是新电脑第一次安装，而之前旧电脑上是可以通过conda create -n命令创建。搞得一头雾水，为什么呢？难道是版本问题？还是现在的版本要访问的网络源被墙了？一顿猜测实践后，终于解决。没有任何技巧，纯经验。

首先打开安装好的anaconda navigator，初始化后在图形界面是可以创建的。

之后我们便可在命令行界面查看已经创建好的环境：

C:\Users\dell>conda env list
WARNING: The conda.compat module is deprecated and will be removed in a future release.
