“ bs4.FeatureNotFound：安装lxml后找不到具有您请求的功能的树生成器：lxml”

Question

我正在尝试使用Beautiful Soup来解析XML文档。这是我实例化BeautifulSoup对象的代码：

with open(filename, encoding='utf-8') as f_:
    content = f_.read()
xml_cont = BeautifulSoup(content, 'lxml')

我运行代码时收到以下错误：

  File "[omitted]", line 13, in [omitted]
    xml_cont = BeautifulSoup(content, 'lxml')
  File "/Users/Josh/Library/Python/3.7/lib/python/site-packages/bs4/__init__.py", line 228, in __init__
    % ",".join(features))
bs4.FeatureNotFound: Couldn't find a tree builder with the features you requested: lxml. Do you need to install a parser library?

我进行了快速搜索，并用pip安装了saw。我是这样做的。

lxml

但是，我仍然遇到错误！关于为什么的任何想法？

Answer 1

BeautifulSoup（content，'html.parser'）您应该试试这个
