我们一起学习┏(^0^)┛
自我介绍,我是一个python迈过基础游荡在爬虫自学之路的一只小蚂蚁。在计算机编程漫长枯燥的道路上,很多技术博客帮助了我,心怀感激,想把自己的经历也记录下来,这是我的第一篇博客,如有瑕疵请多包涵,谢谢~对了,如果你也是自学入门的,来试试hackerrank.com,我只是需要一个队友~你会有不一样的感受的^_^
安装第三方库经常报错:error: microsoft visual c++ 14.0 is required. get it with "microsoft visual c++ build tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
下载:https://download.microsoft.com/download/5/f/7/5f7acaeb-8363-451f-9425-68a90f98b238/visualcppbuildtools_full.exe?fixforie=.exe. 安装挺久,但一劳永逸有木有哈哈?
安装selenium,chromedriver.exe地址:http://chromedriver.storage.googleapis.com/index.html?path=2.41/()
我的是windows系统,文件放在python/scripts目录下,不用配置环境变量。本文只用chrome爬虫。
照教程爬了猫眼排行榜还是啥也不懂的我,接了朋友给的艰巨任务:智联招聘(【内牛满面】)
所学库不多,但好歹迈出了第一步。对代码运行结果也有困惑,希望交流~
