我在centos 7.3上使用nginx。
我在https://certbot.eff.org/#centosrhel7-nginx
上安装了certbot运行certbot --nginx时存在错误：
[root@demo src]# certbot --nginx
Traceback (most recent call last):

我该怎么办？
尝试 pip install --upgrade --force-reinstall 'requests==2.6.0' urllib3，我遇到了同样的问题https://niuhp.com/other/https-certbot.html
这是因为" python-urllib3.noarch"的安装失败：
$ sudo yum install python2-certbot-nginx
...
Installing : python-urllib3-1.10.2-5.el7.noarch 11/37
Error unpacking rpm package python-urllib3-1.10.2-5.el7.noarch
error: unpacking of archive failed on file /usr/lib/python2.7/site-packages/urllib3/packages/ssl_match_hostname: cpio: rename
...
Installed:
python2-certbot-nginx.noarch 0:0.27.1-1.el7
Dependency Installed:
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
解决方案：
根据上述错误消息，只需重命名dir" ssl_match_hostname"（in/usr/lib/python2.7/site-packages/urllib3/packages/）喜欢" ssl_match_hostname.old"，您可以删除新生成的链接（例如：" ssl_match_hostname; 5bf4fd46"），然后再次安装python-urllib3.noarch。这对我有用。
