为什么调用scrapy是出现incremental模块未找到的错误，求各路大神解答
下面是我测试是否安装成功scrapy的语句
(17.5.0)C:Usersxiongjun>scrapy -h
Traceback (most recent call last):
File “e:programdataanaconda3librunpy.py”, line 193, in run_module_as_main
“main”, mod_spec)

from twisted._version import version as version
File “e:programdataanaconda3libsite-packages wisted_version.py”, line 8, in
from incremental import Version
ModuleNotFoundError: No module named ‘incremental’
incrementa模块没找到
但是我已经安装了这个模块
语句如下：
C:Usersxiongjun>pip install incremental
Requirement already satisfied: incremental in e:programdataanaconda3libsite-packages
显示已经安装成功
但是调用scrapy的时候出现一下错误（注scrapy已经安装成功）
