在win 7上安装scrapy（64

2018-06-24 16:37:18

我试图为python2.6安装scrapy，但它似乎不太好。这里是安装的软件包：

G:Python26Scripts>pip freeze
Scrapy==0.16.4
Twisted==12.3.0
libxml2-python==2.7.7
lxml==2.3.6
pyopenssl==0.13
w3lib==1.2
zope.interface==3.8.0

我也有iconv和zlib。这是用pip安装scrapy时的日志。我不知道接下来该做什么，我错过了什么？需要说明，谢谢。

win 7 64位，安装了Visual C ++

ImportError: DLL load failed: %1 is not a valid Win32 application

你需要按照这里的说明（上面也列出）。

问题中列出的具体的DLL错误是由于（至少在我的情况下）安装32位OpenSSL与64位的一切。在我安装了正确的OpenSSL之后（顺便说一下，不得不卸载上面链接中的所有软件包，并为依赖项msi安装程序启动过度顺序），scrapy在python27，windows7,64位上工作正常。

请阅读本指南以在Windows 7上安装scrapy。egenix-pyopenssl被列为必需软件包，并且安装pywin32也可能有所帮助。

在我的情况下，我没有升级导致这个问题的python。
一个简单的scrapy升级没有诀窍

pip安装 - 升级Scrapy

同时安装正确版本的pywin：http://doc.scrapy.org/en/latest/intro/install.html#windows
