[lilyLovesJeans]

I have a question , I can't install the module requests_html on MacOS Catalina ,
and have errors as follows , Can you help me ?

  *********************************************************************************
  Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?
  Perhaps try: xcode-select --install
  *********************************************************************************
  error: command '/usr/bin/clang' failed with exit code 71
  [end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
