我有一个运行 Amazon Linux 第 2 版 (Karoo) 的 EC2 虚拟机 我怎样才能获得certbot？
它附带awscli安装的工具，这些工具似乎与certbotin epel 不兼容：
$ sudo bash
# yum install -y epel-release
# yum-config-manager --enable epel
# yum install certbot certbot-dns-route53
# certbot certonly --dns-route53 --dns-route53-propagation-seconds 30 -d mysite.com
An unexpected error occurred:
ContextualVersionConflict: (botocore 1.13.36 (/usr/lib/python2.7/site-packages), Requirement.parse('botocore<1.6.0,>=1.5.0'), set(['boto3']))
Please see the logfile '/tmp/tmpVO1RPd/log' for more details.
此处简要讨论：https ://community.letsencrypt.org/t/contextualversionconflict-botocore-1-12-92/94922和此处：https ://unix.stackexchange.com/questions/415874/certbot-and- awscli-require-different-versions-of-botocore/456362#456362但这些修复对我不起作用（我想同时拥有 awscli）。
所以我尝试将它安装在 Python venv 中，这样我就可以拥有 certbot 和 awscli，但我得到了这个：
$ sudo bash
# yum install pip
# pip install virtualenv
# virtualenv env
# source env/bin/activate
# pip install certbot certbot-dns-route53
# certbot certonly --dns-route53 --dns-route53-propagation-seconds 30 -d mysite.com

有谁知道如何解决？我尝试安装一些与语言环境相关的不同东西，但还没有运气。
