我在Fedora 20上安装了Scrapy，当我尝试创建一个新项目时，它给了我以下错误：
/usr/lib/python2.7/site-packages/Twisted-14.0.0-py2.7-linux-x86_64.egg/twisted/internet/_sslverify.py:184: UserWarning: You do not have the service_identity module installed. Please install it from <https://pypi.python.org/pypi/service_identity>. Without the service_identity module and a recent enough pyOpenSSL tosupport it, Twisted can perform only rudimentary TLS client hostnameverification. Many valid certificate/hostname mappings may be rejected.
我尝试搜索模块service_identity，但徒劳无功！
在这方面有谁能帮助我。

尝试pip install service_identity来解决此问题。
