Pyinstaller with Sys.Argv[] - “Failed to Execute Script”?

[ironfelix717]

My desperate attempt to find a solution....


I am trying to compile an .EXE on Windows 10 64-bit with PyInstaller. When using the following CMD in Windows CMD prompt, I get a successful execution of the script:

pyinstaller --onefile Mainscript.py

This works fine executing from CMD prompt with arguments (see Python code below). However, the console appears when executing. So, I re-compile to .exe with the following CMD...

pyinstaller --noconsole --onefile Mainscript.py

Now, when running my program via cmd line with arguments, i get "Failed to Execute Script" and i am wondering why.

This occurs due to -w or --onefile i believe. Script runs fine without --onefile.

I call my script and pass arguments via cmd line. 2 of the arguments are paths and i use relative path:

start MainScript.exe "TestPDF.pdf" "TestJPG.jpg" 100

Here is script:

#REQUIRES PDF2IMAGE INSTALLED WITH PIP
#REQUIRES POPPLER BINARIES INSTALLED ON WINDOWS VIA WEBSITE
from pdf2image import convert_from_path
import os.path
import ctypes
import sys

try:
    argcount = len(sys.argv)  #COUNT OF CMD LINE ARGUMENTS
    if argcount != 4:
        if argcount == 1:
            errStr = "No arguments passed"
        else:
            errStr = "Error: incomplete args passed.  " + "Args = " + str(argcount)

            for x in range(1, argcount):  #argv[0] IS ALWAYS THE SCRIPT NAME
                errStr = errStr + str(x) + ": " + sys.argv[x] + "\n"

        ctypes.windll.user32.MessageBoxW(0, errStr, "Python Convert2Thumbnail", 1)
    else:
        inpath = sys.argv[1]
        outpath = sys.argv[2]
        fsize = sys.argv[3]

        pages = convert_from_path(inpath, fsize)
        firstpage = pages[0]
        firstpage.save(outpath, 'JPEG')

except Exception as e:
    errmsg = getattr(e, 'message', repr(e))
    for x in range(1, argcount): 
        errStr = errStr + str(x) + ": " + sys.argv[x] + "\n"
    errStr = errStr + "\n" + "\n" + errmsg
    ctype
