App Fails To Launch But Works From Terminal

[bradyjensen1115]

I've done a fair bit of poking around trying to resolve this but can't seem to make any progress. I have an application that works well when run through the debugger. I then followed the steps and used py2app to generate the application. It processes completely but when when I try to launch the app directly I get the generic 'Launch Error' message. When I launch the application from dist in the terminal, it runs without issue.

Any ideas what might be going on or what I can do to see more details about what is causing this to fail?

Same problem on MacOS Ventura (production) with Python3. First time building Python and py2app so assumed it was me but the app runs in the IDE and runs in the Terminal window from dist folder. Generic Launch error from Finder.

What is interesting to me is that my app uses tkinter and pops a window up before the launch error. Also, the app reads an ugly CSV file, processes it and creates a new CSV file. That file IS created on my Desktop (as designed) but is empty. It fill properly from the command line interface. That tells me it isn't a "launch" error but an executable/run time error.

Has anyone else seen this or have any recommendations? The app is for my own use so I don't need to package for distribution on other systems.

Well, I broke down my code to the smallest component and it appears to be with the "for" loop through the CSV file. In the code below, I can open and parse the file but I can't iterate using the for loop. That causes the Terminate on startup but works when run from the dist CLI and inside the IDE PyCharm. It does not appear to be access issues as removing the for loop works. Any thoughts?

`import csv

with open('/Users/michael/Desktop/exportCsvCheckAccountMovementList.action.csv', mode='r') as csv_file: csv_reader = csv.reader(csv_file, delimiter=',') for row in csv_reader: print (row[0]) `

[mlandesman]

In the words of Emily Latilla, "Nevermind". It turns out the problem is in the data, not the code but it is still a problem for py2app. The data file from a mexican bank contains diacritics (accented characters). These work just in from the CLI and from inside the interpreter but crash the .APP file created by py2app. I wrote a small routine to clean the file first (using standard open().read() command but that crashes also so it is not the csv.reader function. If I clean the file first (using the same code in the interpreter to generate a clean file) then run the .APP again it works perfectly. It just can't open and process the quoted characters. Any suggestions would be greatly appreciated. Perhaps there is an environment change to change the language or character set unless py2app only works on English-language code and data.

Turn off argv_emulation in your setup.py. The step that fails here is: NSMenuItem initWithTitle:action:keyEquivalent: which is called by Tkinter which gets confused by argv_emulation.

Thanks @ExamDay! Worked for me 👍
