我無法弄清楚為什么我的 python 腳本可以運行，但是當嘗試使其成為可執行文件時它不起作用

Question

我在將腳本作為可執行文件運行時遇到問題。 我相信它與 MEIXXXXX 有關，但我不確定如何補救。 下面的腳本在 python 3.10.5 中運行時運行完美，但是當我創建可執行文件時，該文件不會保存或創建。

import os
from tkinter import Button, Entry, Label, Tk

import barcode
from barcode.writer import ImageWriter

root = Tk()
root.minsize(400, 200)

# Add Title from Filename

title = os.path.basename(__file__)[0:-3]
root.title(title.title())

# Get the path of the running file

fp = os.path.dirname(__file__)
os.chdir(fp)


def calculated(event=None):
    # Define content of the barcode as a string
    # Get entry as an input for the barcode 11 char or 12 if you know the checksum digit.
    number = e1.get()
    # calulate the checksum and store the full barcode in the variable 'cs'
    cs = barcode.UPCA(number).get_fullcode()
    # print(cs)
    # Get the required barcode format
    barcode_format = barcode.get_barcode_class("upc")

    # Generate barcode and render as image
    my_barcode = barcode_format(number, writer=ImageWriter())

    # Save barcode as PNG

    my_barcode.save(cs)


lbl1 = Label(root, text="Enter UPC-A code : ")
lbl1.grid(column=0, row=0)
e1 = Entry(root)
e1.grid(column=1, row=0, ipadx=5, padx=5, pady=5)
btn1 = Button(root, text="Calculate", command=calculated)
btn1.grid(column=2, row=0)
root.bind('<Return>', calculated)
root.mainloop()

Answer 1

這些是我為使其工作而采取的步驟。

1. mkdir newdir和cd newdir
2. py -m venv venv and venv\Scripts\activate
3. py -m pip install --upgrade pip pyinstaller pillow python-barcode
4. touch main.py

主程序

import os
from tkinter import Button, Entry, Label, Tk
import barcode
from barcode.writer import ImageWriter

root = Tk()
root.minsize(400, 200)

# Add Title from Filename

title = os.path.basename(__file__)[0:-3]
root.title(title.title())


def calculated(event=None):
    # Define content of the barcode as a string
    # Get entry as an input for the barcode 11 char or 12 if you know the checksum digit.
    number = e1.get()
    # calulate the checksum and store the full barcode in the variable 'cs'
    cs = barcode.UPCA(number).get_fullcode()
    # print(cs)
    # Get the required barcode format
    barcode_format = barcode.get_barcode_class("upc")

    # Generate barcode and render as image
    my_barcode = barcode_format(number, writer=ImageWriter())

    # Save barcode as PNG
    path = os.path.join(os.getcwd(),cs)  # <--- added this
    my_barcode.save(path)


lbl1 = Label(root, text="Enter UPC-A code : ")
lbl1.grid(column=0, row=0)
e1 = Entry(root)
e1.grid(column=1, row=0, ipadx=5, padx=5, pady=5)
btn1 = Button(root, text="Calculate", command=calculated)
btn1.grid(column=2, row=0)
root.bind('<Return>', calculated)
root.mainloop()

我做了一些非常小的改動，以確保將圖像寫入用戶當前目錄，而不是將它們寫入臨時運行時文件夾。

5. pyinstaller -F main.py
6. 在main.spec添加一個元組，其中包含條形碼 fonts 文件夾的路徑和應用程序運行時的目標路徑。

主要規范

a = Analysis(
    ['main.py'],
    pathex=[],
    binaries=[],
    datas=[('./venv/Lib/site-packages/barcode/fonts', './barcode/fonts')], # add this
    ...

7. pyinstaller main.spec
8. dist\main.exe

就是這樣。
