# CentOS7 安装Certbot 报错 #

执行 `certbot certonly` 报错如下：

网上的方法如果你去测试可能会发现`pip show pyOpenSSL` 的版本是 `17.x.x`，这个时候，先删除所有的`yum remove certbot && pip uninstall pyOpenSSL`，再重新安装如下依赖：

yum install -y python-devel
    yum install -y openssl-devel

(以上两句是关键，然后再重新安装certbot)

再次执行`certbot certonly`会出现如下报错：

[root@f2 ~]# certbot certonly
    Traceback (most recent call last): File "/usr/bin/certbot", line 9, in <module> load_entry_point('certbot==0.19.0', 'console_scripts', 'certbot')() File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 570, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2751, in load_entry_point return ep.load() File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2405, in load return self.resolve() File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2411, in resolve module = __import__(self.module_name, fromlist=['__name__'], level=0) File "/usr/lib/python2.7/site-packages/certbot/main.py", line 19, in <module> from certbot import client File "/usr/lib/python2.7/site-packages/certbot/client.py", line 11, in <module> from acme import client as acme_client File "/usr/lib/python2.7/site-packages/acme/client.py", line 34, in <module> urllib3.contrib.pyopenssl.inject_into_urllib3() File "/usr/lib/python2.7/site-packages/urllib3/contrib/pyopenssl.py", line 112, in inject_into_urllib3 _validate_dependencies_met() File "/usr/lib/python2.7/site-packages/urllib3/contrib/pyopenssl.py", line 147, in _validate_dependencies_met raise ImportError("'pyOpenSSL' module missing required functionality.

这个时候已经快大功告成了，执行升级即可：

pip install pyOpenSSL
    pip install PyOpenSSL
