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
然后安装了Scrapy:
D:\home\Python\Scripts\pip install Scrapy
安装似乎有效。但是执行一个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,因为我在网络应用程序环境中。
甚至可以在Azure Web App上运行Scrapy或Portia,还是必须在Azure上使用完全成熟的虚拟机?
谢谢!
答案 0 :(得分:2)
您无法在Azure Web App上“运行”通用Windows应用程序。作为Web应用程序在Azure上运行的东西必须专门构建才能这样做。 因此,您必须在Azure上使用完整的虚拟机。
Azure Webapps似乎可以运行一些Python应用程序,如果它们构建在某些框架上: Jade
