No module _cffi_ freezing with cx_Freeze - python

I am developing a PySide application (Qt for Python) and I would like to freeze it using cx_Freeze.
When I run python setup.py build using my setup file below, it creates the build directory without errors, but then when I run the .exe file generated, I get the error message shown below:
from cx_Freeze import setup, Executable
target = Executable(
script="main_window.py",
base = "Win32GUI",
icon="images\\icon.ico"
)
setup(name = "DemiurgoXMLgen" ,
version = "0.1" ,
description = "" ,
options={'build_exe': {'include_files': ['images\\']}},
executables = [target])
I think it has something to do with the Paramiko package I am using in my application. Has anyone encountered and solved this problem?

I think I solved it by modifying setup.py as below:
import os.path
PYTHON_INSTALL_DIR = os.path.dirname(os.path.dirname(os.__file__))
build_exe_options = {"include_files" : [
os.path.join(PYTHON_INSTALL_DIR, "DLLs", "libcrypto-1_1-x64.dll"),
os.path.join(PYTHON_INSTALL_DIR, "DLLs", "libssl-1_1-x64.dll")]}
build_exe_options = {"packages": ['cffi', 'cryptography'], 'include_files': ['images\\', os.path.join(PYTHON_INSTALL_DIR, "DLLs", "libcrypto-1_1-x64.dll"),
os.path.join(PYTHON_INSTALL_DIR, "DLLs", "libssl-1_1-x64.dll")]}
target = Executable(
script="main_window.py",
base = "Win32GUI",
icon="images\\icon.ico"
)
setup(name = "DemiurgoXMLgen" ,
version = "0.1" ,
description = "" ,
options={'build_exe': build_exe_options},
executables = [target])
and modifying in paramiko->ed25519key.py the import:
from cryptography.hazmat.backends import default_backend
from cryptography.hazmat.backends import openssl as openssl_backend
Essentially:
explicitly specify the import of cffi and cryptography in build_exe_options
copy the dlls for libcrypto-1_1-x64.dll and libssl-1_1-x64.dll
explicitly specify the backend as openssl_backend instead of default_backend

Unable to compile with cx_freeze and PySide2

I have a python program I'm trying to compile with cx_freeze. The GUI I'm using is PySide2.
I've tried including PySide2, here is excluding it, but I keep getting the same error. Below is my setup.py code
from cx_Freeze import setup, Executable
import sys
includefiles = ['README.md', 'debug.log','tcl86t.dll', 'tk86t.dll', 'field.jpg', 'inputClass.py', 'mainfile.qml', 'MyTabView.qml', 'PlayerSelection.qml', 'selectedPlayers.py', 'Settings.qml', 'SimOutput.qml', 'simulationOutput.py']
includes = ["idna.idnadata", "atexit"]
excludes = ["PySide2"]
import os
os.environ['TCL_LIBRARY'] = r'C:\Users\pimat\AppData\Local\Programs\Python\Python36\tcl\tcl8.6'
os.environ['TK_LIBRARY'] = r'C:\Users\pimat\AppData\Local\Programs\Python\Python36\tcl\tk8.6'
setup(name = "Simulation",
version = "0.2",
description = "Optimization Simulator",
options = {'build_exe':{'includes':includes,'excludes':excludes,'include_files':includefiles}},
executables = [Executable("main.py")])
The program compiles fine, but when running the exe, I get the following error:
"ModuleNotFoundError: No module named 'PySide2'"
So the error was that I had installed cx_freeze with python 3.6, but all of my packages were in a python 3.7 folder. I simply copied and pasted into the 3.6 folder and changed the code a bit, and the exe works great.
from cx_Freeze import setup, Executable
import sys
# dependencies
build_exe_options = {
"packages": ["os", "sys", "re", "idna.idnadata", "atexit", "PySide2.QtCore", "PySide2.QtWidgets", "PySide2.QtUiTools", "PySide2.QtQuick", "PySide2.QtQml", "PySide2.QtGui", "shiboken2"],
"include_files": ['README.md', 'debug.log','tcl86t.dll', 'tk86t.dll', 'field.jpg', 'inputClass.py', 'mainfile.qml', 'MyTabView.qml', 'PlayerSelection.qml', 'selectedPlayers.py', 'Settings.qml', 'SimOutput.qml', 'simulationOutput.py',
],
"excludes": ["Tkinter", "Tkconstants", "tcl", ],
"build_exe": "build",
#"icon": "./example/Resources/Icons/monitor.ico"
}
executable = [
Executable("main.py",
base="Win32GUI",
targetName="Simulation.exe"
)
]
setup(name = "Simulation",
version = "0.2",
description = "Simulator",
options={"build_exe": build_exe_options},
executables=executable
)
T'was a dumb mistake, but I've made worse

cx_Freeze common lib folder between executables

I'm compiling a suite of python scripts into executables. I'm using cx_Freeze in order to do so.
The rather common problem is that the lib folder becomes very large. I have excluded modules as much as possible to reduce the size of this but it is still quite sizeable.
Since I am compiling multiple executables, is it possible to have a single shared lib folder that gets referenced by them all to reduce disk size?
An example setup.py is as follows:
import sys, os
from cx_Freeze import setup, Executable
base = None
if sys.platform == 'win32':
base = 'Win32GUI'
executables = [
Executable('MYSCRIPT.py', base=base)
]
additional_mods = ["numpy.core._methods", "numpy.lib.format"]
exclude_mods = ["babel", "scipy", "PyQt5", "tornado", "zmq", "sphinx", "sphinx_rtd_theme", "psutil", "notebook", "nbconvert", "lxml", "cryptography", "bottleneck", "matplotlib"]
build_exe_options = {"excludes": exclude_mods, "includes": additional_mods, "optimize": 1}
os.environ['TCL_LIBRARY'] = r'C:\ProgramData\Anaconda3\tcl\tcl8.6'
os.environ['TK_LIBRARY'] = r'C:\ProgramData\Anaconda3\tcl\tk8.6'
setup(name='MYSCRIPT',
version='0.1',
includes = ['os'],
options = {"build_exe": build_exe_options},
description='MYSCRIPT',
executables=executables
)
Yes it is possible. The trick is to use a single setup.py where the multiple scripts are added to the executables list.
Take for example the following pair of console-based scripts which both use numpy:
main1.py:
import numpy
print('Program 1, numpy version %s' % numpy.__version__)
input('Press ENTER to quit')
main2.py:
import numpy
print('Program 2, numpy version %s' % numpy.__version__)
input('Press ENTER to quit')
You can freeze this scripts at once with cx_Freeze using the following setup.py:
from cx_Freeze import setup, Executable
base = None
executables = [Executable('main1.py', base=base),
Executable('main2.py', base=base)]
additional_mods = ["numpy.core._methods", "numpy.lib.format"]
build_exe_options = {"includes": additional_mods}
setup(name='MYSCRIPTS',
version='0.1',
options={"build_exe": build_exe_options},
description='MYSCRIPTS',
executables=executables)
You get then two executables main1.exe and main2.exe sharing the same lib folder containing numpy.

ImportError: The 'six' package is required

I'm trying to convert my tkinter python script into exe with cx_Freeze. From now on, I've dealt with many common problems TCL-TK, DLL and idna. It seems I solved them but now I have another problem. When I try to run the exe version of the application, I get the following error:
ImportError: The 'six' package is required; normally this is bundled with this package so if you get this warning, consult the packager of your distribution.
import cx_Freeze
import sys
import os.path
PYTHON_INSTALL_DIR = os.path.dirname(os.path.dirname(os.__file__))
os.environ['TCL_LIBRARY'] = os.path.join(PYTHON_INSTALL_DIR, 'tcl','tcl8.6')
os.environ['TK_LIBRARY'] = os.path.join(PYTHON_INSTALL_DIR, 'tcl', 'tk8.6')
base = None
if sys.platform == 'win32':
base = 'Win32GUI'
executables = [cx_Freeze.Executable ("SeeWord.py", base=base)]
cx_Freeze.setup(name="SeeWord",
options= {"build_exe": {"packages": ["idna", "tkinter",

KeyError: 'TCL_LIBRARY' comes out when I use cx_Freeze [duplicate]

When I use cx_Freeze I get a keyerror KeyError: 'TCL_Library'while building my pygame program. Why do I get this and how do I fix it?
My setup.py is below:
from cx_Freeze import setup, Executable
setup(
name = "Snakes and Ladders",
version = "0.9",
author = "Adam",
author_email = "Omitted",
options = {"build_exe": {"packages":["pygame"],
"include_files": ["main.py", "squares.py",
"pictures/Base Dice.png", "pictures/Dice 1.png",
"pictures/Dice 2.png", "pictures/Dice 3.png",
"pictures/Dice 4.png", "pictures/Dice 5.png",
"pictures/Dice 6.png"]}},
executables = [Executable("run.py")],
)
You can work around this error by setting the environment variables manually:
set TCL_LIBRARY=C:\Program Files\Python35-32\tcl\tcl8.6
set TK_LIBRARY=C:\Program Files\Python35-32\tcl\tk8.6
You can also do that in the setup.py script:
os.environ['TCL_LIBRARY'] = r'C:\Program Files\Python35-32\tcl\tcl8.6'
os.environ['TK_LIBRARY'] = r'C:\Program Files\Python35-32\tcl\tk8.6'
setup([..])
But I found that actually running the program doesn't work. On the cx_freeze mailinglist it was mentioned:
I have looked into it already and no, it is not just a simple recompile --
or it would have been done already! :-)
It is in progress and it looks like it will take a bit of effort. Some of
the code in place to handle things like extension modules inside packages
is falling over -- and that may be better solved by dropping that code and
forcing the package outside the zip file (another pull request that needs
to be absorbed). I should have some time next week and the week following
to look into this further. So all things working out well I should put out
a new version of cx_Freeze before the end of the year.
But perhaps you have more luck ... Here's the bug report.
Instead of setting the environment variables using installation specific absolute paths like C:\\LOCAL_TO_PYTHON\\... you may also derive the necessary paths dynamically using the __file__ attribute of Python standard package like os:
import os.path
PYTHON_INSTALL_DIR = os.path.dirname(os.path.dirname(os.__file__))
os.environ['TCL_LIBRARY'] = os.path.join(PYTHON_INSTALL_DIR, 'tcl', 'tcl8.6')
os.environ['TK_LIBRARY'] = os.path.join(PYTHON_INSTALL_DIR, 'tcl', 'tk8.6')
After this fix the executable file will be created, but you will probably get a "DLL not found error" when you try to execute it - at least with Python 3.5.3 and cx_Freeze 5.0.1 on Windows 10.
When you add the following options, the necessary DLL-files will be copied automatically from the Python-Installation directory to the build-output of cx-Freeze and you should be able to run your Tcl/Tk application:
options = {
'build_exe': {
'include_files':[
os.path.join(PYTHON_INSTALL_DIR, 'DLLs', 'tk86t.dll'),
os.path.join(PYTHON_INSTALL_DIR, 'DLLs', 'tcl86t.dll'),
],
},
}
# ...
setup(options = options,
# ...
)
Just put this before the setup at setup.py
import os
os.environ['TCL_LIBRARY'] = "C:\\LOCAL_TO_PYTHON\\Python35-32\\tcl\\tcl8.6"
os.environ['TK_LIBRARY'] = "C:\\LOCAL_TO_PYTHON\\Python35-32\\tcl\\tk8.6"
And run it:
python setup.py bdist_msi
This worked fine for me.
If you get following error with python 3.6:
copying C:\LOCAL_TO_PYTHON\Python35-32\tcl\tcl8.6 -> build\exe.win-amd64-3.6\tcl
error: [Errno 2] No such file or directory: 'C:\\LOCAL_TO_PYTHON\\Python35-32\\tcl\\tcl8.6'
Simply create LOCAL_TO_PYTHON dir in C:\ then create Python35-32 dir inside it. Now copy tcl dir from existing Python36 dir (in C:\) into Python35-32.
Then it works fine.

D. L. Müller's answer need to be modified for cx_Freeze version 5.1.1 or 5.1.0. In these versions of cx_Freeze, packages get frozen into a subdirectory lib of the build directory. The TCL and TK DLLs need to be moved there as well. This can be achieved by passing a tuple (source, destination) to the corresponding entry of the include_files list option (see the cx_Freeze documentation).
Altogether the setup.py script needs to be modified as follows:
import os.path
PYTHON_INSTALL_DIR = os.path.dirname(os.path.dirname(os.__file__))
os.environ['TCL_LIBRARY'] = os.path.join(PYTHON_INSTALL_DIR, 'tcl', 'tcl8.6')
os.environ['TK_LIBRARY'] = os.path.join(PYTHON_INSTALL_DIR, 'tcl', 'tk8.6')
# ...
options = {
'build_exe': {
'include_files':[
(os.path.join(PYTHON_INSTALL_DIR, 'DLLs', 'tk86t.dll'), os.path.join('lib', 'tk86t.dll'))
(os.path.join(PYTHON_INSTALL_DIR, 'DLLs', 'tcl86t.dll'), os.path.join('lib', 'tcl86t.dll'))
],
},
}
# ...
setup(options = options,
# ...
)
The initial KeyError problem:
This worked for me with python 3.7 on windows 7:
from cx_Freeze import setup, Executable
import os
import sys
where = os.path.dirname(sys.executable)
os.environ['TCL_LIBRARY'] = where+"\\tcl\\tcl8.6"
os.environ['TK_LIBRARY'] = where+"\\tcl\\tk8.6"
build_exe_options = {"include_files": [where+"\\DLLs\\tcl86t.dll", where+"\\DLLs\\tk86t.dll"]}
setup(
name = "SudoCool",
version = "0.1",
description = "Programme de SUDOKU",
options={"build_exe": build_exe_options},
executables = [Executable("sudoku.py")]
)
Now cx_Freeze is working:
My application is working:

cx_Freeze: cannot input ExcelFormulaParser

So I am trying to compile my code into an .exe using cx_freeze.
Here is the code I am using to compile it...
from cx_Freeze import setup, Executable
import sys
import numpy.core._methods
import numpy.lib.format
from xlwt import ExcelFormulaParser
additional_mods = ['numpy.core._methods', 'numpy.lib.format']
setup(name='ReconApp',
version='0.1',
description='xyz.script',
options = {'build_exe': {'includes': additional_mods}},
executables = [Executable("reconciliation_application.py")])
The code compiles enter image description herewith no errors.
When I go to run the .exe the program launches and closes with this error.
I notice that it does not like something inside xlwt module ExcelFormulaParser
By I do not know what the error is.
any suggestions?
Try to add xlwt library to setup options, i.e.
import sys, os
from cx_Freeze import setup, Executable
build_exe_options = {"packages": ["numpy", "matplotlib", "xlwt"]}
setup(
name = "App",
version = "1.0",
description = "App ...",
options = {"build_exe": build_exe_options},
executables = [Executable("App.py", base = "Win32GUI")])
