PyInstaller + tkdnd/tkinterdnd2 "Unable to load tkdnd library" when launching frozen exe. Works when launched from script

Question

In my script I am using tkinterdnd2 library to achieve drag and drop functionality from Windows explorer into my tkinter UI.

from tkinterdnd2 import TkinterDnD, DND_FILES
import tkinter as tk

class TkWindow:
    def __init__(self):
        self.window = TkinterDnD.Tk()
        self.tbox = tk.Listbox(self.window)
        self.tbox.pack(fill=tk.BOTH)
        self.tbox.drop_target_register(DND_FILES)
        self.tbox.dnd_bind('<<Drop>>', self.tk_files_dropped)
        self.window.mainloop()

    def tk_files_dropped(self, event):
        messagebox.showinfo("x", event.data)

TkWindow()

When I launch the script - everything works.

But when I freeze the project to a single EXE with PyInstaller, and run it, I get this error:

I tried this solutions already:

1. I added the pyinstaller-hook as instructed in the tkinterdnd2 repository:

   from PyInstaller.utils.hooks import collect_data_files, eval_statement
datas = collect_data_files('tkinterdnd2')

2. I add --collect-all tkinterdnd2 when executing build command.

3. I tried copying tkdnd2.8 to tcl8.6 as mentioned in this answer

4. I tried getting rid of venv and installing all the packages directly into base python interpreter.

Answer 1

I used --collect-all TkinterDnD2 with upperCase.

Answer 2

Use this now when converting a Python file to exe(pyinstaller.exe --collect-all TkinterDnD2 --windowed yor_app.py) And then you will find the files and folders of the program that was created, you will find a file named TCL. Copy the tkdnd folder into it and then run the exe file
