I use nginx on centos 7.3.
I installed certbot following https://certbot.eff.org/#centosrhel7-nginx
There is an error when running certbot --nginx:
[root@demo src]# certbot --nginx
Traceback (most recent call last):

ImportError: No module named 'requests.packages.urllib3'解决方法：
trypip install --upgrade --force-reinstall 'requests==2.6.0' urllib3 , I've had the same problem https://niuhp.com/other/https-certbot.html
