我在目标节点上安装/构建Ansible代理时经常使用的步骤之一是pip2 install pyOpenSSL。这是Ansible客户端的一个要求，以便使用标准Ansible模块创建自签名证书，例如openssl_certificate
从今天起这就不管用了。
我可以把这封信转载如下：

vagrant init generic/ubuntu1804
vagrant ssh
sudo su -
apt-get update && apt-get -y install python python-pip
pip2 install pyOpenSSL

最后一步失败，并显示以下消息。目前在Ubuntu 18.04上安装pyOpenSSL的正确方法是什么？是否有解决此问题的方法？
或者更好的是，有没有Ansible的Python发行版？它包括所有依赖项，这样我就不必编译构建自己的Ansible客户端了？

cffi需求设置为cffi!=1.11.3,>=1.8，新版本1.3存在一些问题。
您可以安装pyOpenSSL之前的1.12.3版本：

pip2 install cffi==1.12.3
pip2 install pyOpenSSL

PS，您可以在此处找到问题：https://bitbucket.org/cffi/cffi/issues/424/please-rollback-to-1123

我在安装Python包时遇到了同样的问题。对我来说，下面的更新很容易就解决了这个问题：

pip3 install -U pip

然后我安装了软件包，这是在我的情况下paramiko.
