windows 64位操作系统下,用 Python 抓取网页,并用 pyQuery 解析网页

pyQuery是jQuery在python中的实现,能够以jQuery的语法来操作解析HTML文档,十分方便。使用前需要安装,easy_install pyquery即可,或者Ubuntu下
详情参考:

但是用pip命令安装pyquey的时候,报错了

pip install pyquery

提示需要先安装 lxml ,于是用如下命令安装 lxml

pip install lxml

 报错

Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?

技术分享

查资料,知乎上找到如下解决方案:https://www.zhihu.com/question/30047496 亲测有效。

1. 安装wheel,命令行运行:
pip install wheel
2.在这里下载对应的.whl文件,注意别改文件名! http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml
3. 进入.whl所在的文件夹,执行命令即可完成安装
pip install 带后缀的完整文件名

从上面的地址下载到适合我电脑的whl文件:lxml-3.6.4-cp27-cp27m-win_amd64.whl

然后在安装 pyquery,成功搞定!

C:\Python27\Scripts>pip install lxml-3.6.4-cp27-cp27m-win_amd64.whl
Processing c:\python27\scripts\lxml-3.6.4-cp27-cp27m-win_amd64.whl

C:\Python27\Scripts>pip install pyquery
