django - Heroku: string without NULL bytes with several requirements files -


i'm trying deploy django web application in heroku ubuntu following "two scoops of django 1.6" project structure.

after doing heroku create, run git push heroku master , output attached @ end.

i googled extensively , i'm aware error this

typeerror: must encoded string without null bytes, not str

and caused because encoding or rare characters in requirements files. problem tried saving less dependencies , changing encodings in files , achieved nothing (i don't know valid encodings heroku, i'm blind @ this).

i'm looking way of finding null characters, cat -e @ command line, can't find anything. i'm asking way finding encoding problem or wrong dependency.

thank in advanced.


edit: tried doing pip 

install -r <filename>.txt

with several of requirements txt files. installations fine. tried doing git push heroku master commented in main requirements.txt (an empty file) , keeps giving same error. maybe heroku not picking requirements.txt file???

i tried re-creating files command line , typing manually same content (not copy-paste). same error keeps appearing. :-(

files , output:

my requirements files are:

requirements.txt (at root of project):

# file here because many platforms service # requirements.txt in root directory of project. -r requirements/production.txt

requirements/production.txt:

# pro-tip: try not put here. there should no dependency in # production isn't in development. -r base.txt  gunicorn==18.0

and requirements/base.txt:

django==1.7 psycopg2==2.6 sqlparse==0.1.15 django-debug-toolbar==1.3.0 html5lib==0.999 pillow==2.8.1 pypdf2==1.24 reportlab==3.1.44 six==1.9.0 xhtml2pdf==0.0.6

the output:

it fault. super-newbie stupid error. not making git commit after each edit, pushing same wrong files heroku.

now realized, , when pushing error has changed one.

thanks lot , sorry making lose time.
