Install -r 309 traceback

Non sono riuscito ad installare django 3 0 9, con pip install -r Django-3.0.9-py3-none-any.whl
... mi segnala ben 11 traceback, di cui l'ultimo è in
lib/encodings/cp1252.py, line 15, in decode return codecs.charmap_decode(input,errors,decoding_table)
Non ho internet sul pc, e deve scaricare i files sullo smart.
Come posso fare?
