我正在尝试让Scrapy继续我的macbook但是，在pip安装Scrapy并完成所有工作之后，当我导入它时它会给我错误
ImportError:
dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/lxml/etree.so, 2): Library not loaded: libxml2.2.dylib
Reason: Incompatible library version: etree.so requires version 12.0.0 or later, but libxml2.2.dylib provides version 10.0.0
我应该怎么做才能解决这个问题，这样我才能最终开始学习Scrapy？ ：（
