Error building executable using pyinstaller #7052
Description
Building executables which include astropy seem to have a history of issues (e.g. #960 (comment)). Initially I was getting an,
ImportError: Astropy requires the 'six' module of minimum version 1.10, which I solved by using a trick given in the above PR:
I was able to get this to work using PyInstaller with the following pyinstaller options
--exclude-module astropyand--add-data path_to/astropy:astropy-- @fridgerator
Now I get the new error:
Traceback (most recent call last):

[2338] Failed to execute script pyapi
I'm using a virtualenv named vetest in the directory ve_test, trying to run with the command:
pyinstaller -F pyapi.py --exclude-module astropy --add-data /Users/lzkelley/Programs/cosmo/ve_test/vetest/lib/python3.5/site-packages/astropy:astropy
The full output from pyinstaller is attached.
An additional issue is that the resulting executable is >200MB, is that normal? The application I'm trying to package is really just using the astropy.cosmology.LambdaCDM class. Might there be a better way to include that alone?
