解决方案：
solutions Scrapy can work with Python 3 on windows if you make some minor adjustments: Copy the _win32stdio and _pollingfile to the appropriate directory under site-packages. Namely, twisted-dirinternet. Download these fromhttps://github.com/twisted/twisted/tree/trunk/twisted/internet URLS: https://github.com/twisted/twisted/blob/trunk/src/twisted/internet/_win32stdio.py URLS: https://github.com/twisted/twisted/blob/trunk/src/twisted/internet/_pollingfile.py pip install pypiwin32 Granted, this is based on my personal experience. Because the repository will certainly change in the future, readers should beware the age of this answer. 来源： http://stackoverflow.com/questions/37342603/importerror-cannot-import-name-win32stdio
