ConnectionError(ReadTimeoutError("HTTPSConnectionPool(host='repo.anaconda.com', port=443): Read timed out.",),)
A reportable application error has occurred. Conda has prepared the above report.
If submitted, this report will be used by core maintainers to improve
future releases of conda.

Thank you for helping to improve conda.
Opt-in to always sending reports (and not see this message again)
by running
$ conda config --set report_errors true具体原因应该是不支持https，将https 改为http即可
1、在cmd中输入%HOMEPATH%目录打开，编辑其中的 .condarc 文件（记事本打开即可）
2、修改文件
删除 - default
将 - https://... 改成 - http://...修改后效果如下：
3、修改后运行情况
完美解决！！！
