要在virtualenv下安装它,您应该首先安装所需的包.在ubuntu上:

sudo apt-get install python-dev libffi-dev libssl-dev

然后你可以输入:

pip install pyopenssl

应该是`libffi-dev` (4认同)

pyOpenSSL 0.13引入了对(S)erver(N)ame(I)ndication TLS扩展的支持.此扩展允许客户端告诉服务器他们希望与之通信的主机名,允许服务器选择合适的证书来呈现.

在OpenSSL 0.9.8f中引入了对SNI的支持.因此,pyOpenSSL 0.13将使用OpenSSL 0.9.8f或更高版本构建,但不构建OpenSSL 0.9.8e或更早版本,其中不希望包含它所期望的API.

也许较新版本的pyOpenSSL会使这些绑定成为可选,恢复对OpenSSL 0.9.8e及更早版本的支持.但是,类似地,较新版本的OpenSSL也可以与pyOpenSSL 0.13一起使用.

pyOpenSSL项目发布预发布.预发布的广泛测试可以帮助避免像这样的情况.我建议任何依赖pyOpenSSL的人订阅(非常低流量)的pyOpenSSL用户列表(或者在SourceForge上),并在发布完成之前进行预发布时进行的测试.

那就对了!我有同样的问题,我发现安装pyOpenSSL 0.12比将openssl从0.9.8e升级到0.9.8f更容易让0.13工作..这是我使用的命令:easy_install http://pypi.python.org/包/源/ p/pyOpenSSL/pyOpenSSL-0.12.tar.gz (16认同)
Thanasis和Jean-Paul,非常感谢您提供的信息.希望我几个小时前找到这个页面,或者可以帮助我们帮助我解决这个问题.我刚刚放弃了在Centos5上进行scrapy的工作.再次感谢! (3认同)
