FeatureNotFound: Couldn't find a tree builder with the features you requested: lxml. Do you need to install a parser library

问题描述

在学习《PYTHON网络爬虫从入门到实践》一书时，用 jupyter notebook 运行书中代码时遇到如下报错

FeatureNotFound: Couldn't find a tree builder with the features you requested: lxml. Do you need to install a parser library

出错原因

由于PYTHON3中没有html解析器，即lxml

解决方法

sudo pip3 install lxml

安装完重新启动 jupyter notebook 即可

BeautifulSoup支持多种解析器，如Python标准库中的html.parser，以及第三方的 lxml 和 html5lib。如果你指定了一个未安装的解析器，比如lxml，就会出现这个错误。安装缺失的解析器库lxml。（如果还有类似的问题就是缺少解析库，通过pip安装即可。BeautifulSoup在初始化时未能找到指定的解析器。，即可查看已安装的python库。

我刚开始学些爬虫，用的是Pycharm编译器，在爬虫的时候用到了BeautifulSoup，里面涉及到lxml，如下图所示： 运行之后便报如下错误：bs4.FeatureNotFound: Couldn’t find a tree builder with the features you requested: lxml. 百度过后才发现，这里报错的意思是：你的开发环境下下载的包里不存在你需要的lxml，目录下有没有你需要的包，如果没有就安装一个。就是这么简单。 所以对于使用Pycharm的人来说，通过
