Pyinstaller - ImportError: No system module 'pywintypes' (pywintypes27.dll)

Question

I am trying to package my python script into an executable. I thought I would be pretty straight forward as I don't have very many imports. First off here are my imports:

from __future__ import print_function 
from netCDF4 import Dataset
import numpy as np
import os
from progressbar import Percentage,Bar,ETA,ProgressBar,RotatingMarker  

I know for a fact that numpy is supported I'm not sure about __future__ or os and I know for sure that netCDF4 and progressbar are not supported. I am using pyinstaller version 2.1 on Python 2.7.7 for Windows 7, and here is the command I use to start creating .exe:

C:\Users\Patrick\Desktop\netcdf_grid_extraction>pyinstaller --onefile --hidden-i
mport=netCDF4 --hidden-import=progressbar netcdf_grid_extraction.py

Here is a list of errors. There seems to be one major problem with not being able to find the module pywintypes.dll, as well as two assemblies related to amd64_Microsoft. Here is a list of the 4 errors I get. How can I go about solving these?

And here are the warnings I get that may or may not be relevent and are both related to not being able to find ctypes

890 WARNING: library python%s%s required via ctypes not found
2175 WARNING: library python%s%s required via ctypes not found

The good news is that its seems the third party modules are being accounted for however I am not sure if they are associated with the errors that I am gettting:

4540 INFO: Hidden import 'netCDF4' has been found otherwise
4540 INFO: Hidden import 'progressbar' has been found otherwise
4540 INFO: Hidden import 'codecs' has been found otherwise
4545 INFO: Hidden import 'encodings' has been found otherwise

Answer 1

I just copied the DLL pywintypes27.dll in C:\Python27\Lib\site-packages\pywin32_system32.
I added it in win32/lib.

It's OK!
