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

报错原因：找不到清华源镜像

conda创建环境报错,环境/软件安装,conda,python,开发语言

解决办法

#step1: 删除原有镜像
(base) tuolong@tuolong-20:~/anaconda3/envs$ conda config --remove-key channels
#step2: 添加默认镜像
(base) tuolong@tuolong-20:~/anaconda3/envs$ conda config --append channels conda-forge --append channels bioconda --append channels defaults
