从 cron 运行时，Let's Encrypt certbot-auto setuptools 版本出现错误

CentOS 6，certbot 0.16.0。当我以 root 身份手动运行它（而不是通过 sudo）时，一切正常。当我设置 /etc/crontab 以自动运行它时，它返回一个错误：

Error: couldn't get currently installed version for //.local/share/letsencrypt/bin/letsencrypt: 
//.local/share/letsencrypt/lib64/python2.6/site-packages/cryptography/__init__.py:26: DeprecationWarning: Python 2.6 is no longer supported by the   Python core team, please upgrade your Python. A future version of cryptography will drop support for Python 2.6

我尝试了 Let's Encrypt 社区，发现有人遇到了同样的问题，但他们提供的唯一帮助就是迁移到 bash 脚本。我更愿意修复官方脚本。

这是问题：

HOME=/

为了修复此问题，需要将具有 /root 值的 HOME 变量传递给脚本：

env HOME=/root /path/to/certbot-auto
