Hola, buenas noches o buenos dias dependiendo de donde lean. Queria pedirles una ayudita con un problema que estoy teniendo al tratar de instalar la herramienta pwndb.

Al ejecutar el siguiente comando: pip3 install -r requirements.txt --root
Me sale esto:

 ile "/usr/local/bin/pip3", line 6, in <module>
    from pkg_resources import load_entry_point
  File "/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 3251, in <module>    
    @_call_aside                                                                                     
  File "/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 3235, in _call_aside 
    f(*args, **kwargs)                                                                               
  File "/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 3264, in _initialize_master_working_set
    working_set = WorkingSet._build_master()
  File "/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 585, in _build_master
    return cls._build_from_requirements(__requires__)
  File "/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 598, in _build_from_requirements
    dists = ws.resolve(reqs, Environment())
  File "/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 786, in resolve
    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'pip==20.2.2' distribution was not found and is required by the application

El error que no me deja terminar con la instalacion creo yo que es: DistributionNotFound: The 'pip==20.2.2' distribution was not found and is required by the application

Busque en internet pero aparentemente este error no le habra pasado a mucha gente ya que no pude encontrar nada, les agradeceria un monton su ayuda. Espero tengan una buena semana. Saludos.

pip3 install -U pip
