Windows- Pyinstaller Error failed to execute script When App Clicked

Question

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

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

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

In case anyone doesn t get results from the other answers  I fixed a similar problem by    adding --hidden-import flags as needed for any missing modules cleaning up the associated folders and spec files    rmdir  s  q dist  rmdir  s  q build  del  s  q my service spec   Running the commands for installation as Administrator

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

Well I guess I have found the solution for my own question  here is how I did it   Eventhough I was being able to successfully run the program using normal python command as well as successfully run pyinstaller and be able to execute the app  new app exe  using the command line mentioned in the question which in both cases display the GUI with no problem at all  However  only when I click the application it won t allow to display the GUI and no error is generated    So  What I did is I added an extra parameter --debug in the pyinstaller command and removing the --windowed parameter so that I can see what is actually happening when the app is clicked and I found out there was an error which made a lot of sense when I trace it  it basically complained that  some image jpg  no such file or directory   The reason why it complains and didn t complain when I ran the script from the first place or even using the command line      is because the file image existed in the same path as the script located but when pyinstaller created  dist  directory which has the app product it makes a perfect sense that the image file is not there and so I basically moved it to that dist directory where the clickable app is there

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

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   For more information visit this documentation page
