PyInstaller cannot check for assembly dependencies - python-3.6

Question

I am trying to make Tkinter GUI module with a build option to build Exes after the user puts some inputs & I don't want him to install python and pyinstaller to be able to Compile the code to Exe.
Using Python 3.6.0
I made 2 python scripts first-named compiler.py & other hello.py
hello.pyprint("Hello World")
compiler.py
import PyInstaller.__main__
import ctypes
import win32ctypes
from win32ctypes import pywin32
from win32ctypes.pywin32 import pywintypes
import os
def compiling():
PyInstaller.__main__.run([
# '--name=%s' % package_name,
'--onefile',
'--windowed',
# '--add-binary=%s' % os.path.join('resource', 'path', '*.png'),
# '--add-data=%s' % os.path.join('resource', 'path', '*.txt'),
# '--icon=%s' % os.path.join('resource', 'path', 'icon.ico'),
os.path.join('hello.py'), # my_package is a Directory
# '--version-file=%s' % os.path.join('assembly.txt'),
])
compiling()
when I try to Compile compiler.py with pyinstaller it compiles successfully
with -->pyinstaller --onefile --console compiler.py
but when I try to run the exe it throws
PyInstaller cannot check for assembly dependencies.
Please install pywin32-ctypes.
pip install pywin32-ctypes
What I Have Tried?
1-i installed pywin32-ctypes successfully
2-Tried to compile compiler.py with different alternatives other than pyinstaller
3-cx-freeze & nuitka both of them throw the same error when I Run after compiling.
4- tried using Python 3.7.5 on other machine start new fresh Throw the Same Error
the reason I choose pyinstaller because it can build 1 EXE

Unable to run PyInstaller - "Please install PyWin32 or pywin32-ctypes"
All those Failed As Well is it something I am Doing Wrong or is Pyinstaller Problem

Answer 1

An old question but maybe someone could face the same issue.
I found a solution and it works for me.
Installing this module solves the problem
pip install cffi
After installing, I tried the build again. Gives error-like warning.
Traceback (most recent call last):
File "<string>", line 2, in <module>
ModuleNotFoundError: No module named 'win32com'
Traceback (most recent call last):
File "<string>", line 2, in <module>
ModuleNotFoundError: No module named 'win32com'
You can fix this warning via installing pywin32
pip install pywin32
I hope it helped someone else.

Answer 2

I had the exact same issue.
The fix for me was making an edit to a couple of lines in the Pyinstaller compat.py file.
Navigate to your python directory -> Lib -> site-packages -> Pyinstaller.
Open compat.py and look for the following:
if is_win:
try:
from win32ctypes.pywin32 import pywintypes # noqa: F401
from win32ctypes.pywin32 import win32api
except ImportError:
# This environment variable is set by seutp.py
# - It's not an error for pywin32 to not be installed at that point
if not os.environ.get('PYINSTALLER_NO_PYWIN32_FAILURE'):
raise SystemExit('PyInstaller cannot check for assembly dependencies.\n'
'Please install pywin32-ctypes.\n\n'
'pip install pywin32-ctypes\n')
Change both of those import statements to import the modules themselves instead of trying to grab them from win32ctypes.pywin32.
#from win32ctypes.pywin32 import pywintypes # noqa: F401
#from win32ctypes.pywin32 import win32api
import pywintypes
import win32api
I hope that helps!

I solved this on Windows on command prompt, first navigate using cd, till reach the folder Scripts:
C:\Users\john\Envs\yourEnv\Scripts
You'll see a pyinstaller.exe
Then call it on cmd:
pyinstaller --onefile --clean --name myApp "C:\path\to\your\script\example.py"
The resulting folders will be Dist and Build and they will be on first path you see here "C:\Users\john\Envs\yourEnv\Scripts". The file .exe is on Dist.

Answer 4

I had similar issue.The above methods didnt work.I used env method ,(env) C:\Users\RAMAJAYAM>python -m PyInstaller --name "tkinterapp1.py" "C:\Users\RAMAJAYAM\tkinterapp1.py" and compiled successfully.Exe works fine.

Answer 5

Ok I think I have figure it out the pip3 install pyinstaller was installing it in the ~\AppData\Roaming\Python\Python37\Scripts directory. I had to to uninstall it via pip3 uninstall pyinstaller. Then navigate to the python3 root install directory then run python.exe -m pip install pyinstaller.
Not sure what this means, but I'm no longer getting the following error:
PyInstaller cannot check for assembly dependencies.
Please install pywin32-ctypes.
pip install pywin32-ctypes

Answer 6

Alternatively, it looks like PyInstaller doesn't like running in a virtual environment. deactivateing the venv, then pip install pyinstaller and pyinstaller pyinstaller.spec worked for me.

Answer 7

I had the same issue and had to upgrade pyinstaller using
pip install --upgrade pyinstaller
It must be some kind of problem with the packages pyinstaller uses, It might have updated the packages while upgrading pyinstaller too.

Answer 8

i got this broblem too.
i fixed it...
first -> uninstall pywin32-ctypes -> pip uninstall pywin32-ctypes
second -> install again -> pip install pywin32-ctypes
maybe this working ..!
