我正在尝试在 Microsoft Azure Web App 上运行 Scrapy 或 Portia。我通过创建虚拟环境安装了 Scrapy：
D:\Python27\Scripts\virtualenv.exe D:\home\Python
然后安装 Scrapy：
D:\home\Python\Scripts\pip install Scrapy
安装似乎工作。但是执行蜘蛛会返回以下输出：

文档http://doc.scrapy.org/en/latest/intro/install.html说我必须安装pywin32。我不知道如何通过命令行下载/安装它，因为我在 Web 应用程序环境中。
甚至可以在 Azure Web 应用程序上运行 Scrapy 或 Portia，还是我必须在 Azure 上使用成熟的虚拟机？
谢谢！
