Scrapy教程扭曲錯誤

Question

我是Scrapy的新手，僅對python有基本了解。
運行Scrapy教程時遇到錯誤。
我安裝了Windows 7操作系統，64位和32位Python 2.7.12
到目前為止我已經采取的步驟

• 按照安裝頁面執行的步驟並設置“ scrapy”虛擬環境
• 激活虛擬環境
• 已安裝scrapy（所有依賴項似乎也都安裝正確，包括pywin（32位版本））
• 按照教程頁面運行步驟
• scrapy startproject tutorial
• 使用教程頁面上給出的代碼創建文件quotes_spider.py

• 從scrapy \\ Scripts \\ tutorial我運行了scrapy crawl quotes並得到以下錯誤

   (scrapy) F:\\My Projects\\scrapy\\Scripts\\tutorial>scrapy crawl quotes 2016-11-05 14:21:59 [scrapy] INFO: Scrapy 1.2.1 started (bot: tutorial) 2016-11-05 14:21:59 [scrapy] INFO: Overridden settings: {'NEWSPIDER_MODULE': 'tutorial.spiders', 'SPIDER_MODULES': ['tutorial.spiders'], 'ROBOTSTXT_OBEY': True, 'BOT_NAME': 'tutorial'} 2016-11-05 14:21:59 [scrapy] INFO: Enabled extensions:'scrapy.extensions.logstats.LogStats','scrapy.extensions.telnet.Telne tConsole', 'scrapy.extensions.corestats.CoreStats'] Unhandled error in Deferred: 2016-11-05 14:21:59 [twisted] CRITICAL: Unhandled error in Deferred: 2016-11-05 14:21:59 [twisted] CRITICAL: Traceback (most recent call last): File "f:\\myproj~1\\scrapy\\lib\\site-packages\\twisted\\internet\\defer.py", line 12 60, in _inlineCallbacks result = g.send(result) File "f:\\myproj~1\\scrapy\\lib\\site-packages\\scrapy\\crawler.py", line 90, in crawl six.reraise(*exc_info) File "f:\\myproj~1\\scrapy\\lib\\site-packages\\scrapy\\crawler.py", line 72, in crawl self.engine = self._create_engine() File "f:\\myproj~1\\scrapy\\lib\\site-packages\\scrapy\\crawler.py", line 97, in _create_engine return ExecutionEngine(self, lambda _: self.stop()) File "f:\\myproj~1\\scrapy\\lib\\site-packages\\scrapy\\core\\engine.py", line 68, in __init__ self.downloader = downloader_cls(crawler) File "f:\\myproj~1\\scrapy\\lib\\site- packages\\scrapy\\core\\downloader\\__init__.py" , line 88, in __init__ self.middleware = DownloaderMiddlewareManager.from_crawler(crawler) File "f:\\myproj~1\\scrapy\\lib\\site-packages\\scrapy\\middleware.py", line 58, in from_crawler return cls.from_settings(crawler.settings, crawler) File "f:\\myproj~1\\scrapy\\lib\\site-packages\\scrapy\\middleware.py", line 34, in from_settings mwcls = load_object(clspath) File "f:\\myproj~1\\scrapy\\lib\\site-packages\\scrapy\\utils\\misc.py", line 44, in load_object mod = import_module(module) File "c:\\python27\\Lib\\importlib\\__init__.py", line 37, in import_module__import__(name) File "f:\\myproj~1\\scrapy\\lib\\site- packages\\scrapy\\downloadermiddlewares\\retry.py", line 23, in <module> from scrapy.xlib.tx import ResponseFailed File "f:\\myproj~1\\scrapy\\lib\\site-packages\\scrapy\\xlib\\tx\\__init__.py", line 3, in <module> from twisted.web import client File "f:\\myproj~1\\scrapy\\lib\\site-packages\\twisted\\web\\client.py", line 42, in <module> from twisted.internet.endpoints import TCP4ClientEndpoint, SSL4ClientEndpoint File "f:\\myproj~1\\scrapy\\lib\\site-packages\\twisted\\internet\\endpoints.py", line 36, in <module> from twisted.internet.stdio import StandardIO, PipeAddress File "f:\\myproj~1\\scrapy\\lib\\site-packages\\twisted\\internet\\stdio.py", line 30, in <module> from twisted.internet import _win32stdio File "f:\\myproj~1\\scrapy\\lib\\site- packages\\twisted\\internet\\_win32stdio.py", line 9, in <module> import win32api ImportError: No module named win32api 

這與此處討論的錯誤非常相似，但建議的解決方案似乎無法解決。 pywin已安裝在我的全局環境C：Python27 \\ Lib \\ site-packages中，但未在我的虛擬環境中顯示。 我不確定如何在虛擬環境中安裝它，因為pywin可執行文件似乎只允許在C下安裝。預先感謝您的幫助！

似乎您缺少win32api，只需通過pip安裝它：

pip install pypiwin32
