That warning should not be raised unless we're not using pyOpenSSL、Can you confirm that `pip freeze` lists pyOpenSSL, ndg-httpsclient, and pyasn1?

Oooops! I had convinced myself that pyOpenSSL was installed, but it wasn解决方案

通过研究，我找到了解决这个问题的方法。如果您在Python 2.7.6环境中使用requests 2.6.0，可以通过添加ndg-httpsclient模块来避免警告，并降低pyOpenSSL导入时间的影响。

**解决方案：**

以下是解决问题的步骤：

1、创建一个虚拟环境（如果您尚未创建），并激活它：

```bash
mkvirtualenv requests260_ndghttpsclient
workon requests260_ndghttpsclient

pip install requests==2.6.0 ndg-httpsclient

pip freeze

cffi==0.9.2
cryptography==0.8
enum34==1.0.4
ndg-httpsclient==0.3.3
pyasn1==0.1.7
pycparser==2.10
pyOpenSSL==0.14
requests==2.6.0
six==1.9.0
