Scrapy教程扭曲错误

Question

我是Scrapy的新手，只对Python有一个基本的理解。
运行Scrapy教程时发生错误。
我有一个Windows 7操作系统，64位和32位的Python 2.7.12安装
步骤到目前为止，我已经采取

• 随后的步骤按照安装页面，并建立了一个虚拟环境“scrapy “
• 激活虚拟环境
• 安装scrapy（所有的依赖似乎也已经安装了罚款，包括pywin，32位版本）
• 冉步骤按照教程页面
• 创建的文件quotes_spider.py，与上tutorial page

• 给出从scrapy \脚本代码scrapy startproject tutorial

• \教程中，我跑了scrapy crawl quotes并得到了以下错误

这是很相似的错误讨论here但建议的解决方案似乎并没有解决。 pywin安装在我的全局环境C：Python27 \ Lib \ site-packages中，但它并没有出现在我的虚拟环境中。我不知道如何将它安装在我的虚拟env中，因为pywin可执行文件似乎只允许在C下安装。在此先感谢您的帮助！在虚拟ENV

好像你缺少WIN32API，只需通过PIP安装：

pip install pypiwin32
