Scrapy教程扭曲錯誤

Question

我是Scrapy的新手，只對Python有一個基本的理解。
運行Scrapy教程時發生錯誤。
我有一個Windows 7操作系統，64位和32位的Python 2.7.12安裝
步驟到目前爲止，我已經採取

• 隨後的步驟按照安裝頁面，並建立了一個虛擬環境「scrapy 「
• 激活虛擬環境
• 安裝scrapy（所有的依賴似乎也已經安裝了罰款，包括pywin，32位版本）
• 冉步驟按照教程頁面
• 創建的文件quotes_spider.py，與上tutorial page

• 給出從scrapy \腳本代碼scrapy startproject tutorial

• \教程中，我跑了scrapy crawl quotes並得到了以下錯誤

這是很相似的錯誤討論here但建議的解決方案似乎並沒有解決。 pywin安裝在我的全局環境C：Python27 \ Lib \ site-packages中，但它並沒有出現在我的虛擬環境中。我不知道如何將它安裝在我的虛擬env中，因爲pywin可執行文件似乎只允許在C下安裝。在此先感謝您的幫助！在虛擬ENV

好像你缺少WIN32API，只需通過PIP安裝：

pip install pypiwin32
