SSLError(MaxRetryError(‘HTTPSConnectionPool(host=‘repo.anaconda.com’, port=443): Max retries exceeded with url: /pkgs/main/linux-64/repodata.json.bz2 (Caused by SSLError(SSLError(“bad handshake: Error([(‘SSL routines’, ‘ssl3_get_server_certificate’, ‘certificate verify failed’)])”)))’))

解决方式

1. 更换清华源：

    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 

注意：这里建议不要用https，改为http

2. 将 .condarc 文件中的“- defaults”删除

3. 重新安装，成功：
