无法找出 service_identity 模块错误的原因

Question

Error is:

UserWarning: You do not have a working installation of the service_identity module: 'cannot import name 'verify_ip_address' from 'service_identity.pyopenssl' (C:\\Users\\techn\\Anaconda3\\lib\\site-packages\\service_identity\\pyopenssl.py)'. Please install it from <https://pypi.python.org/pypi/service_identity> and make sure all of its dependencies are satisfied. Without the service_identity module, Twisted can perform only rudimentary TLS client hostname verification. Many valid certificate/hostname mappings may be rejected.

I've tried all other possible answers from several sites but none of them fix my problem. Any insight?

I've tried:

pip install cryptography
pip install cffi --upgrade
pip install service_identity --upgrade
pip install pyopenssl --upgrade

Answer 1

想通了，我需要做conda install service_identity
