获取错误:DLL加载失败:操作系统无法运行%1 - Python 2.7; Scrapy模块; 导入密码学

我无法在Scrapy教程中成功运行第一个命令(http://doc.scrapy.org/en/latest/intro/tutorial.html).粘贴在下面的代码副本是结果(最后有错误).

安装了Python 2.7,我按照scrapy的安装说明进行操作(http://doc.scrapy.org/en/latest/intro/install.html).我在Windows 7(64位)上运行Python 2.7.6 32位.

安装的其他方面:

Twisted-13.2.0.dist-info

zope.interface-4.1.1-py2.7

Scrapy-0.22.2-py2.7

lxml-3.3.3-py2.7

cssselect-0.9.1-py2.7

cryptography-0.3.dist-info

pyOpenSSL-0.14-py2.7

pywin32_system32

这是错误信息:

我有这个问题是由于另一个(较旧的？)版本的libeay32.dll和ssleay32.dll在我自己的OpenSSL 1.0.1g安装之前在PATH上.我建议您使用SysInternals的Process Monitor来监视python.exe以查看它实际加载OpenSSL DLL的位置.

就我而言,罪犯是C:\Program Files (x86)\Intel\iCLS Client\我的驱动程序附带的一些英特尔组件.在PATH环境变量中先前移动我自己的OpenSSL bin目录之后,一切都按预期工作.

我只是重新安装密码术以使其工作.

pip卸载密码学

pip安装加密
