[python] Windows- Pyinstaller Error "failed to execute script " When App Clicked

I am having a tough time overcoming this error, I have searched everywhere for that error message and nothing seems relevant to my situation:

"failed to execute script new-app" 

new-app is my python GUI program. When I run pyinstaller using this command:

pyinstaller.exe --onedir --hidden-import FileDialog --windowed --noupx new-app.py

It does work smoothly. In addition, when I execute the command line to run the gui program, it works perfectly and the GUI is generated using this command:

.\dist\new-app\new-app.exe

But when I go to that file hopefully to be able to click the app to get the GUI, it gives me the error said above. Why is that?

I am using python2.7 and the OS is Windows 7 Enterprise.

Any inputs will be appreciated and thanks a lot in advance.

I got the same error and figured out that i wrote my script using Anaconda but pyinstaller tries to pack script on pure python. So, modules not exist in pythons library folder cause this problem.

That error is due to missing of modules in pyinstaller. You can find the missing modules by running script in executable command line, i.e., by removing '-w' from the command. Once you created the command line executable file then in command line it will show the missing modules. By finding those missing modules you can add this to your command : " --hidden-import = missingmodule "

I solved my problem through this.

I was getting this error for a different reason than those listed here, and could not find the solution easily, so I figured I would post here.

Hopefully this is helpful to someone.

My issue was with referencing files in the program. It was not able to find the file listed, because when I was coding it I had the file I wanted to reference in the top level directory and just called

"my_file.png"

when I was calling the files.

pyinstaller did not like this, because even when I was running it from the same folder, it was expecting a full path:

"C:\Files\my_file.png"

Once I changed all of my paths, to the full version of their path, it fixed this issue.

In my case i have a main.py that have dependencies with other files. After I build that app with py installer using this command:

pyinstaller --onefile --windowed main.py

I got the main.exe inside dist folder. I double clicked on this file, and I raised the error mentioned above. To fix this, I just copy the main.exe from dist directory to previous directory, which is the root directory of my main.py and the dependency files, and I got no error after run the main.exe.

Add this function at the beginning of your script :

import sys, os 
    def resource_path(relative_path):
        if hasattr(sys, '_MEIPASS'):
            return os.path.join(sys._MEIPASS, relative_path)
        return os.path.join(os.path.abspath("."), relative_path)

Refer to your data files by calling the function resource_path(), like this:

resource_path('myimage.gif')

Then use this command:

pyinstaller --onefile --windowed --add-data todo.ico;. script.py

In case anyone doesn't get results from the other answers, I fixed a similar problem by:

1. adding --hidden-import flags as needed for any missing modules

2. cleaning up the associated folders and spec files:

rmdir /s /q dist

rmdir /s /q build

del /s /q my_service.spec

3. Running the commands for installation as Administrator
