Certbot :ImportError: No module named 'requests.packages.urllib3

Question

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):

Answer 1

trypip install --upgrade --force-reinstall 'requests==2.6.0' urllib3 , I've had the same problem https://niuhp.com/other/https-certbot.html

Answer 2

It's because of the installation failure of "python-urllib3.noarch" :

$ sudo yum install python2-certbot-nginx

...
  Installing : python-urllib3-1.10.2-5.el7.noarch                                                                                                                                                     11/37

  audit-libs-python.x86_64 0:2.8.1-3.el7_5.1          certbot.noarch 0:0.27.1-1.el7
...

Failed:
  python-urllib3.noarch 0:1.10.2-5.el7

Solution:

According to error messages as above, just rename that dir "ssl_match_hostname" (in /usr/lib/python2.7/site-packages/urllib3/packages/), like to "ssl_match_hostname.old", and you may remove the new generated link(e.g: "ssl_match_hostname;5bf4fd46"), then install the python-urllib3.noarch again. And this works for me.
