certbot forletsencrypt 缺少 pyopenssl 模块

我需要帮助为 LetsEncrypt 设置 CertBot

我在 CentOS 7 上运行 Python 2.7

当我运行 certbot 时，出现以下错误：

[root@li86-193 frappe-bench]#certbot certonly --manual

不要尝试在 CentOS/RHEL 系统上手动安装 certbot。它只会造成巨大的混乱。相反，从 EPEL 安装它。

yum install epel-release
yum install certbot

我运行了 EPEL certbot 包并解决了这个问题。我系统上的其他内容已将“请求”库更新为最新版本（撰写本文时为 2.13.0），但作为 certbot 依赖项安装的 RPM 为 2.6.0。比较`pip list 2>/dev/null 的版本| grep requests` 和 `rpm -q python-requests --queryformat '%{VERSION}\n'`。如果它们不同，请尝试`pip install --upgrade --force-reinstall 'requests==2.6.0'`。 (8认同)
