Pyinstaller on Msys2 with pygobject

I have been building an application on Linux using python pygobject, and now I need to distribute it on Windows.
I first installed pygobject via msys2 (as per the official pygobject documentation)
Now, using msys2/mingw32, I can run my program typing
python3 main.py
But when I try to freeze it into a .exe with Pyinstaller, and try to run the produced .exe
If I Don't use --onefile, I get an import error on the _struct module (whereas "import _struct" works in python shell)
If I use --onefile, I get the Following error :
error:
lib/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-ani.dll could not be extracted!
fopen: No such file or directory
I’m using the devel version of Pyinstaller. I know next to nothing on Windows OS… does anyone know how to fix that error ?

It sounds like you were on the right path, unfortunately you ran in to a bug in PyInstaller. The good news is that the issue with the No module named '_struct' error is now fixed and released in version 3.6 and later. I would recommend using the --onedir mode of PyInstaller, you should be able to successfully package a GTK app for Windows.

how to fix the "__path__ attribute not found" error for packages installed by pip installer?

I recently installed the opencv package using pip install and I wrote a small code to test it (cvtest.py). The code runs through the python idle shell but running it though the command prompt gives the error
Error while finding module specification for 'cvtest.py' (ModuleNotFoundError: __path__ attribute not found on 'cvtest' while trying to find 'cvtest.py')
I tried uninstalling and reinstalling both python and the package. looking up the system path using python -m site gives these results. I am the only user of my laptop.
sys.path = [
'C:\\Users\\Kareem Mostafa\\Desktop\\Assignments\\computer vision',
'G:\\Python37\\python37.zip',
'G:\\Python37\\DLLs',
'G:\\Python37\\lib',
'G:\\Python37',
'G:\\Python37\\lib\\site-packages',
This is the code I am using
import cv2
x=cv2.imread('backpack for sale.jpg',0)
cv2.imshow('x',x)
update: the problem is happening with all the py files I am having whether they require imports or not. apparently python is looking for _init_.py for all the files as if they are packages. Any idea what is going on?

For anyone else that had this problem (assuming kareemostafa has fixed it now!)
Removing the .py suffix on the python -m command fixes this problem, it appears -m only requires module names whereas running it directly as a python file (no -m option) requires the .py suffix
In your case python -m cvtest should be sufficient.

how to build .exe for python 3.5+, 3.6 if possible?

Is there now an easy protocol to build a .exe from python 3.5+, using modules pyqtgraph, qt5, theano, pymc3, numpy, scipy, os and sys, and opening a simple GUI stored in a '.ui' file ? I lost hours and eventually failed to make one (for w7-64 bits). Help !
preliminary failure with py2exe: I first install py2exe for python 3 but it turns out this is not compatible with my python 3.6 yet, so I downgraded to python 3.5… to get a bunch of errors. Then I went to forums and tried the proposed cures but failed (I’m uneasy with windows), the alternative being to downgrade to python 3.4… So I downgraded to python 3.4 to get an error concerning a missing ‘msvcr100.dll’ that I tried to install following instructions on forums but by default I don’t have the permission to modify system directories… When I eventually had this permission it turns out the ‘regsvr32’ command fails (isn’t this for 32 bits ? but there is no ‘regsvr64’…). Following episodes are described below.
update august 23, 2017, 1pm:
I also tried pyinstaller as advised but it failed (see my related question build a .exe for Windows from a python 3 script importing theano with pyinstaller)
I also tried cx_freeze but it failed (see my related question build a .exe for Windows from a python 3 script)
I also tried pynsist but it fails (same link than above)
what's next ?
update september, 2, 2pm:
I eventually managed to build a .exe with pyinstaller after many episodes.
Unfortunately I failed to deal with the ‘theano’ module (that is required in my case by the ‘pymc3’ module) and I had to modify the .py files and give up part of the application. Could anyone help me building a .exe for windows 7+, with the ‘theano’ module ?
see build a .exe for Windows from a python 3 script importing theano with pyinstaller

Pyinstaller Works with Python 3.5 and it is working even for packages like tensor-flow, scipy , etc (The packages I worked with)
py -3.5 pip install pyinstaller
then go the C:\Users\user\AppData\Local\Programs\Python\Python35\Scripts
and run the command
pyinstaller <code .py file along with directory> --onefile
--onefile : is for compressing the build and get a single file as output

I would suggest pyinstaller see http://www.pyinstaller.org/
The pyinstaller already supports 3.5
The development version supports 3.6

It is better to use spec file to import other hidden libraries. I listed all Sklearn libraries and add them to spec file as a hiddenimports, you can add libraries you used in your project.

Pyinstaller import error: zope.interface not found

I am trying to create standalone exe of twisted application using PyInstaller. Everything is ok, even executable file is getting build, but its not working. I mean if try to execute it gives error 'Import error: Twisted requires zope.interface 3.6.0 or later: no module named zope.interface."
I already have installed zope.interface 4.1.0. Also twisted application is running fine, with 'python ' But at the time of building executable file Pyinstaller is unble to import zope.interface.
How to solve this issue?
Thank you in advance.

finally problem solved.
Problem is zope.interface is not getting added in PYTHONPATH.
Actually I have tried different setups (like pip & exe), though it was not getting added. Exact reason I don't know.
But after installing zope.interface using 'easy_install ', it is added in PYTHONPATH & I am able to create executable file.
Thank you for taking interest.

Maybe it'll help in your problem: http://github.com/kpdyer/fteproxy/issues/66

Python: _socket.so

Greetings!
So I'm creating a Python script that will when finished be compiled with Shedskin. Currently we do a little FTP work in this script so we import the ftplib module. When I attempt to compile it with Shedskin we get the error back saying that there is no '_socket' file in our Python2.6 installation on Ubuntu. I've checked myself in the '/usr/lib/python2.6/lib-dynload' dir to confirm that yes there isn't any file entitled '_socket.so' present in that folder.
I've tried reinstalling the python2.6 package in Synaptic but to no avail.
What should I do?

Look for shdeskin supported library modules in
/usr/lib/python2.6/site-packages/shedskin/lib/.
My Fedora installation of shdeskin 0.7 does not include ftplib.
