Tengo dificultades para usar pip para instalar casi cualquier cosa. Soy nuevo en la codificación, así que pensé que tal vez esto es algo que he estado haciendo mal y he optado por easy_install para obtener la mayor parte de lo que necesitaba, que generalmente ha funcionado. Sin embargo, ahora estoy tratando de descargar la biblioteca nltk, y ninguno de los dos está haciendo el trabajo.
Intenté entrar
sudo pip install nltk
pero obtuve la siguiente respuesta:

--easy_install installed fragments of the library and the code ran into trouble very quickly upon trying to run it.
¿Alguna sugerencia en este asunto? Realmente agradecería algunos comentarios sobre cómo puedo hacer que pip funcione o algo para solucionar el problema mientras tanto.
