Certbot：ImportError：没有名为“requests.packages.urllib3”的模块

Question

我在centos上使用nginx7.3。

我在https://certbot.eff.org/#centosrhel7-nginx之后安装了certbot

运行certbot --nginx时出错：

[root@demo src]# certbot --nginx
Traceback (most recent call last):

Answer 1

trypip install --upgrade --force-reinstall 'requests==2.6.0' urllib3，我也遇到了同样的问题https://niuhp.com/other/https-certbot.html

Answer 2

是因为“python-urllib3.noarch”安装失败：

$ 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

解决方案：

根据上面的错误信息，只需将该目录重命名为“ssl_match_hostname” （在/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。
