Question

每当我尝试使用pip安装任何模块时都会出现此错误，但easy_install工作正常。我的Ubuntu 12.04机器中没有配置代理。以前它工作正常，只是知道，它是如何突然停止工作的。

这是我在运行sudo pip install <any_package_name>时遇到的错误：

我找到了一个潜在的解决方案here。这是相关的引用：

“发生这种情况是因为Ubuntu 12.04（这是我服务器的操作系统）的旧pyOpenSSL库不接受属性'set_tlsext_host_name'。要解决此问题，您需要添加依赖pyOpenSSL＆gt; = 0.13。在Ubuntu上进行更新pyOpenSSL使用pip，您还需要安装libffi-dev并按python-openssl删除apt。“

$ sudo apt-get purge python-openssl
$ sudo apt-get install libffi-dev
$ sudo pip install pyOpenSSL

如果不清楚或者它对你不起作用，请告诉我。

使用pip安装任何模块时出错，但easy_install有效
