I have created a desktop gui application which i want to package. I was directed to use pyinstaller to package it so i did. I have a mainwindow.py file where i import a resource file (converted to python code) as well as other imports going on in there. However when i run the output file,it gives me an error. I suspected it was due to my resource file, from the error so i tried pyinstaller on one of the modules and it worked perfectly. however i keep getting an error with the MainWindow.py file. I have the image of the error here for your consideration. How do i go around this error?
I have managed to solve the problem. After reading this answer, I tried pyrcc4 with the '-py3' flag and it worked. I think without the py3 flag,the resource file is converted into a python 2.x code. And I was trying to interpret py2 code with py3 interpreter. That's my understanding of the problem tho. But in case you have a similar problem,try using the -'py3' flag for python3 interpreter.Good Luck

I am new with programming, so it is maybe harder for me to understand but I have the following issue:
I have a script that imports "eurostag.dll", which according to its manual, should work until Python 3.6. (but the manual is not updated, so it may work also with later updates, I assume).\ The issue is that I have Python 3.8. and when running the script I receive the following message:
"Failed to load EUROSTAG library (Could not find module 'D:\Eurostag\eustag_esg.dll' (or one of its dependencies). Try using the full path with constructor syntax.)"
I have tried to move the .dll library where the script is, but nothing changed. I tried also changing the directory with os.chdir, but the same message appears (with the same 'D:\Eurostag\eustag_esg.dll', so the directory was not changed.
Does anybody know if there is any workaround for this?
Thank you!
Based on this Previos Post I'm trying to figure out how to make an exe out of my python files. The main issue seems to be that Pmw and its modules do not seem to import correctly though pyinstaller. The main error says:
FileNotFoundError: [WinError 3] The system cannot find the path specified: 'C:\User\Name\AppData\Local\Temp\_MEI61522\Pmw
Looking at the Pmw init it seems what it's doing is looking for files in the directory which have Pmw_### and looking in there which has lib and then PmwLoader.suffix and loadther then imports all the dependencies
So now it seems pyinstaller isn't understanding this file dependency system created by Pmw and when I tried to follow the previous post instruction I ran into other errors that made the code unable to compile.
If anyone has any insight on this, that would be fantastic
PMW has a script for bundling (almost) everything into one file which I found in Lib\site-packages\Pmw\Pmw_\bin\bundlepmw.py
My version wasn't entirely Python 3 compliant so I had to make a few edits to the file before adding it to my sources.
Ugly but it worked for me.
Welp, I gave up on pyinstaller and downgraded to python 3.4 and used cx_freeze and created created a single Pmw.py file from some code which I found from python-pmw-and-cx-freeze
I am building a GUI tkinter python3 application and attempting to compile it with py2app. For some reason when I try to launch the .app bundle in the dist folder it gives me this error:
A main script could not be located in the Resources folder
I was wondering why it is doing this, as it is rather frustrating, and I can not find anything about it anywhere. I copied my .py file into the resources folder (Networking.py). Previous to this error I also found an error in the Info.plist. In the key where it states the runtime executable, I found it was trying to get python2.7, which I have updated and am no longer using. I changed it to my current version, which the path for looks like this:
/Library/Frameworks/Python.framework/Versions/3.6/Python
It may be worth noting that it had a strange path previously, which did not look like a proper path to me. It was #executable_path/../Frameworks/Python.framework/Versions/2.7/PythonI removed this completely... Was this wrong? I have no idea about anything about XML, which is what it seemed to be...
Also when compiling this happened:
error: [Errno 1] Operation not permitted: '/Users/Ember/dist/Networking.app/Contents/MacOS/Networking'
Any help would be highly appreciated! Thanks!
EDIT
I actually figured out: a bit of a stupid mistake, but since I'm using python 3.x I have to type in python3 before doing it.
In your "setup.py" file that you used to create the application, did you remember to list all the modules used in your code. For example, if you used the OS and Glob modules, then you would add this to your setup.py next to "OPTIONS":
OPTIONS = {'argv_emulation': True, 'includes':['glob', 'os']}
Basically, anything that you import into your module, you should include in the setup.py. Let me know if that works.

I had the same problem.
python setup.py py2app
I tried
python3 setup.py py2app
and it worked just fine. Hope this helps.
I'm having problems while running a compiled source code. The code itself is correct and if I run python file.py everything goes fine; if I compile it with pyinstaller or software like this, and then I run the compiled file it says ImportError: No module named _cffi_backend. But when I open python and import cffi and/or _cffi_backend python doesn't show error. Investigating in my code I found that the problem is just with padding from cryptography, so if I don't import padding the output doesn't show errors (obviously errors comes because the code doesn't work well without padding module).
Can someone help me?
I just ran into this issue as well.
What worked for me was adding in --hidden-import=_cffi_backend option when building with pyinstaller.
When I try to import time I get : No module named time
I have tried other time modules(datetime and timeit) and they work fine. I decided to check my installation and I can't find time.py anywhere. I checked the Lib, Scripts, libs and include folders, but can't find it anywhere.
Anyone know what I can do to fix this? Maybe download the .py and put it in Lib myself?
I am using Python 3.3.5 with PyCharm IDE. Only extra scripts I've installed is EasyInstall and PRAW.
The import does work. When PyCharm said No module named time, I assumed I would get a compiler error and started trying to fix it.
However when I eventually just ran the code it worked fine. I expect PyCharm doesn't detect the time module as it's a dll and not a py as noted by Martijn in the comments. This is on PyCharm Community Edition 4.0.4.
I tried playing with virtualenv and a host of other things, but I eventually went to Preferences -> Build, Execution, Deployment -> Console -> Python Console, and in the "starting script" box, I added two lines:
sys.builtin_module_names.append('sys')
sys.builtin_module_names.append('time')
This got rid of errors I had with both sys and time. Once I did that, I even get autocomplete for both of those modules... weird.
