Python3安裝lxml

原創 COCO56 2020-06-28 05:08 
pip3 install lxml

如果使用國外的源下載速度慢，我們可以使用國內的源進行提速：

  • 豆瓣源
    pip3 install lxml -i https://pypi.douban.com/simple
  • 清華大學源
    pip3 install lxml -i https://pypi.tuna.tsinghua.edu.cn/simple

如果不安裝lxml庫，則在使用時會提示：

bs4.FeatureNotFound: Couldn’t find a tree builder with the features you requested: lxml. Do you need to install a parser library?
