Windows下搭建Python爬虫环境-开发者社区

属于开发爬虫特别平常会用到的语言, 这儿阐述怎样于体系里构建爬虫运行的环境, 涵盖安装必备的工具以及配置相关的组件, 给后续的爬虫开发筑牢根基。

1、安装，推荐使用2.7版本进行配置。

2、可以去官方网站那儿下载对应版本的安装包, 接着依提示完成安装的操作。等安装完了之后, 要把那个安装路径（就比如说C:这样的）添加到系统环境变量范畴里, 目的是为了在命令提示符窗口当中, 直接输入命令就能够启动并且使用程序。

3、通过运行指定命令，系统将自动下载并完成的安装。

4、进行Zope的安装, 从而令接口功能得以加强, 将编程模型实现拓展, 把应用范围予以扩大。

5、欲获取那安装文件, 需前往网站进行访问, 此文件为zope.-4.3.3.win-amd64-py2.7.exe , 它所能适配的是64位系统, 并且对2.7版本予以支持, 待下载完成而后便可直接开展安装并投入使用。

6、运行安装包以完成Zope.的安装步骤。

7、在命令行中运行导入指令，若无报错即代表安装成功。

8、安装以获取事件驱动的网络编程支持

9、执行该命令可自动获取依赖包并完成的下载与安装。

10、借助指定命令, 进行下载, 完成安装, 以此来安装w3lib库, 其目的在于获取网页功能函数, 没错且有上述这种可行的做法。

11、通过命令行执行安装的指令即可完成部署。

12、安装.msi，为编译库提供所需的VC环境支持。

13、下载-2.9.3-cp27-none-.whl这款安装包, 使用它, 借助pip工具, 来完成安装的操作。

14、在命令行那儿执行, C:.7.exe , D:360极速浏览器下载-2.9.3-cp27-none-.whl, 凭借指定路径去安装适用于2.7的库, 以此确保系统环境跟文件相兼容, 操作之前要确认及pip版本准确无误。

15、安装库以支持XML文件的XPath解析功能。

16、用命令安装即可

17、若提示错误，则需执行步骤7进行安装。

18、出现了错误提示, 提示内容为, xslt - 无法被识别成有效命令, 也不是可执行程序, 大概是没有进行安装, 或者环境变量配置存在错误。

19、或批量处理文档

20、最后可安装框架

在开发爬虫时, 中关村在线是极为常用所运用的语言, 本文着重讲述怎样于系统里搭建爬虫得以运行的环境, 其中涵盖安装必备工具以及配置相关组件这两个方面, 以此为后续开展爬虫开发筑牢基础。其一, 安装环节, 推荐选用2.7版本来实施配置。其二, 能够从官方网站下载对应版本的安装包, 依据提示完成安装的相关操作。安装。
