AI摘要

本文介绍了解决conda无法创建虚拟环境及安装第三方包的问题，主要原因是默认镜像源访问速度慢导致的超时错误。通过更换镜像源为清华镜像源并删除默认镜像源，可以有效解决这一问题。

1.问题描述：conda无法创建虚拟环境并且无法安装其他第三方包，报错内容如下：

PS C:\Users\Administrator.DESKTOP-EEN44LR> conda create -n flask_py python=3.8
Collecting package metadata (current_repodata.json): failed

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

2.错误原因：默认镜像源访问速度过慢，会导致超时从而导致更新和下载失败。
