我尝试更新scrapy，当我尝试检查版本时出现以下错误
C:\Windows\system32>scrapy version -v
:0: UserWarning: You do not have a working installation of the service_identity
module: 'No module named service_identity'. Please install it from <https://pyp
i.python.org/pypi/service_identity> and make sure all of its dependencies are sa
tisfied. Without the service_identity module and a recent enough pyOpenSSL to s
upport it, Twisted can perform only rudimentary TLS client hostname verification
. Many valid certificate/hostname mappings may be rejected.
