Python请求和流式处理-AttributeError:'；X509和x27；对象没有属性'_x509和x27；

Python请求存在以下问题：

rs = requests.get(STREAM_URL, stream=True,headers=headers)

这可能是新版本的bug。

在我的例子中，原来pyOpenSSL的版本太旧了。我的Ubuntu 14.4运行的是pyOpenSSL的0.13版。我在elasticsearch python库中收到报告的错误

我必须通过运行以下命令来更新pyOpenSSL：

sudo pip install -U pyOpenSSL

您可以通过以下方式检查pyOpenSSL版本：

python -c 'import OpenSSL; print(OpenSSL.__version__)'

您至少需要PyOpenSSL版本0.14

这对我很有用，来自：

如果遇到AttributeError:“X509”对象没有属性“\u X509”错误，请将请求库的版本从2.12.1降级到2.11.1<代码>使用pip安装请求==2.11.1。

请求问题：必须使用版本2.11.1才能工作。您找到原因了吗？我在ubnutu虚拟机上看到了这种行为，该虚拟机也有请求2.12.1。奇怪的是。我有另一个具有相同请求版本2.12.1的VM，在那里它工作正常！！没有。我只是检查了在其他服务器和本地开发人员上运行的版本。没有一个版本是最新的。我假设代码中存在缺陷或与某些依赖项的兼容性。看起来更像是兼容性问题。您是否有

/usr/lib

vs

/usr/local/lib
