Question

我正在尝试从两个 python 脚本创建一个可执行文件。一个脚本定义了另一个后端脚本的 GUI。后端正在读取 excel 文件，使用它们创建 DataFrame 进行操作，然后输出一个新的 excel 文件。这是在 excel 文件中读取的代码，其中“user_path、userAN、userRev1、userRev2”作为用户输入从 GUI 中获取：

import pandas as pd
import numpy as np
import string
from tkinter import messagebox
import os

def generate_BOM(user_path, userAN, userRev1, userRev2):
    ## Append filepath with '/' if it does not include directory separator
    if not (user_path.endswith('/') or user_path.endswith('\\')):
        user_path = user_path + '/'
    ## Set filepath to current directory if user inputted path does not exist
    if not os.path.exists(user_path):
        user_path = '.'
    
    fileFormat1 = userAN + '_' + userRev1 + '.xls'
    fileFormat2 = userAN + '_' + userRev2 + '.xls'
    
    for file in os.listdir(path=user_path):
        if file.endswith(fileFormat1):
            df1 = pd.read_excel(user_path+file, index_col=None) 
        
        if file.endswith(fileFormat2):
            df2 = pd.read_excel(user_path+file, index_col=None)

通过 Spyder 运行这两个脚本时，一切正常。要创建 exe，我使用 Pyinstaller 和以下命令：

pyinstaller --onefile Delta_BOM_Creator.py

这会导致以下错误：

UnicodeDecodeError: 'utf-8' codec can't decode byte 0x93 in position 3965: invalid start byte

我已经尝试了所有我能找到的与这个问题有些相关的方法。仅列出几个：

UnicodeDecodeError: 'utf-8' codec can't decode byte 0x96 in position 15: invalid start byte

https://www.dlology.com/blog/solution-pyinstaller-unicodedecodeerror-utf-8-codec-cant-decode-byte/

Pandas read _excel: 'utf-8' codec can't decode byte 0xa8 in position 14: invalid start byte

我从来没有用过 Pyinstaller，也从来没有用 python 创建过可执行文件，所以很抱歉我是个大菜鸟。

解决方案：我找到了解决方案。我进入了错误中提到的 codecs.py 文件，并在第 322 行添加了 'ignore'

(result, consumed) = self.buffer_decode(data, 'ignore', final)

使用 Pyinstaller 时出现“UnicodeDecodeError: 'utf-8' codec can't decode byte 0x93 in position 3965: invalid start byte”
