Esta pregunta ya tiene una respuesta aquí:

He instalado Python 2 (64 bit), en Windows 8.1 (64 bit) y quería saber la versión de pip y para eso disparépip --version Pero está dando error.

    C:\Users\ADMIN>pip --version
Traceback (most recent call last):

    six.text_type().join(characters).encode(encoding)
LookupError: unknown encoding: cp65001

Nota: El mismo comando funciona bien para Python 3. He desinstalado ambos e instalado nuevamente pero aún no he tenido éxito.
