F:\bs\bosszp>python bosszp.py

Traceback (most recent call last):
  File "bosszp.py", line 167, in <module>
    get_job(url=url, conn=conn, cursor=cursor, city_name_x="北京")
  File "bosszp.py", line 117, in get_job
    soup = BeautifulSoup(html, 'lxml')
  File "D:\software\DevEnv\Python\lib\site-packages\bs4\__init__.py", line 246, 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?

F:\bs\bosszp>pip install parser
ERROR: Could not find a version that satisfies the requirement parser (from versions: none)

解决方案（无效）

F:\bs\bosszp>pip install html_parser
Collecting html_parser

然后发现不行

最终解决方案

pip install lxml

然后

soup = BeautifulSoup(html, 'lxml')
