Include gspread module using py2exe, pyinstaller

Question

I have created a python application which fetches data from a google spreadsheet and performs the required operation and outputs files with the data accordingly. The application works fine through my ide and the console. I'm using gspread and Tkinter for accessing the google sheets and for the GUI respectively.

However when I try to create it into an exe. I keep running into errors.

First I tried using py2exe but I keep getting the error
ImportError: No module named gspread
My setup.py is

from distutils.core import setup
import py2exe
setup(console = ["app.py"], options={"py2exe":{"includes":["gspread"]}})`

and I run it with the command python setup.py py2exe

I also tried pyInstaller using the command pyinstaller app.py and I get the same error. Although in this case the command executes completely and the exe is created but when I run it the console window flashes saying
ImportError: No module named gspread

I also tried using cx_freeze to create the executable. The command I use is
python setup.py build_exe -s -p gspread,json,oauth2client.client,os

This creates the executable but I get the error

I\O operation failed

for line 187 of my code

credentials = oauth2client.client.GoogleCredentials.get_application_default()
credentials = credentials.create_scoped(['https://spreadsheets.google.com/feeds'])
gc = gspread.authorize(credentials)  #line 187

which I've caught using a try/except block on line 187
