Question

我创建了GUI应用程序，用于将数据从GUI传输到.xlsx格式。以.py运行程序时一切正常，数据导出到文件'choosen_data.xlsx'。但是在使用cx_freeze创建exe文件之后，应用程序正在运行但没有将数据导出到'choosen_file.xlsx'

我读了很多关于冰冻状态和这个功能的信息：

def find_data_file(filename):
if getattr(sys, 'frozen', False):
    # The application is frozen
    datadir = os.path.dirname(sys.executable)
else:
    # The application is not frozen
    # Change this bit to match where you store your data files:
    datadir = os.path.dirname(__file__)

return os.path.join(datadir, filename)

但我不能让它发挥作用。有什么问题？

setup.py

    from cx_Freeze import setup, Executable
import sys, os

# Dependencies are automatically detected, but it might need
# fine tuning.

def find_data_file(filename):
    if getattr(sys, 'frozen', False):
        # The application is frozen
        datadir = os.path.dirname(sys.executable)
        print(str(datadir))
    else:
        # The application is not frozen
        # Change this bit to match where you store your data files:
        datadir = os.path.dirname(__file__)

    return os.path.join(datadir, filename)

data_sheet = find_data_file('data_sheet.csv')
choosen_data = find_data_file('choosen_data.xlsx')

buildOptions = dict(packages = [],
                    excludes = [],
                    include_files = [data_sheet, choosen_data])

import sys
base = 'Win32GUI' if sys.platform=='win32' else None

executables = [
    Executable('main.py', base=base)
]

setup(name='test',
      version = '1.0',
      description = '',
      options = dict(build_exe = buildOptions),
      executables = executables)

我还尝试将文件作为'choosen_data.xlsx'放在include_files中 - 没有用。

我的main.py文件的开头

#-*- coding: utf-8 -*-
from PyQt5 import QtGui
from PyQt5 import QtWidgets
import sys 
import design  things
import csv, sqlite3
from openpyxl import load_workbook
import os

def find_data_file(filename):
    if getattr(sys, 'frozen', False):
        # The application is frozen
        datadir = os.path.dirname(sys.executable)
    else:
        # The application is not frozen
        # Change this bit to match where you store your data files:
        datadir = os.path.dirname(__file__)

    return os.path.join(datadir, filename)

choosen_data = find_data_file('choosen_data.xlsx')


class ExampleApp(QtWidgets.QMainWindow, design.Ui_MainWindow):


    def __init__(self):

        super(self.__class__, self).__init__()
        self.setupUi(self)

        self.pushButton.clicked.connect(lambda: self.update_xlsx(choosen_data,
                                                            comboboxes_list,labels_list))

内置文件夹

prt_screen_of_dirs

也许这些信息很重要：我将cx_freeze-quickstart复制到我的应用程序的文件夹中，与我的主文件并排运行。像那样：

folder with main.py and cx_freeze

我还试图以两种方式修改openpyxl主目录中的 init .py文件（没有结果，数据仍未导出）

1.改变此行

here = os.path.abspath(os.path.dirname(__file__))

到此：

here = os.path.abspath(os.path.dirname(sys.executable))

2。并添加全新的功能，如：

    import json
import os
import sys

def find_data_file(filename):
    if getattr(sys, 'frozen', False):
        # The application is frozen
        datadir = os.path.dirname(sys.executable)
    else:
        # The application is not frozen
        # Change this bit to match where you store your data files:
        datadir = os.path.dirname(__file__)

    return os.path.join(datadir, filename)

try:
##    here = os.path.abspath(os.path.dirname(sys.executable))
    here = find_data_file(__file__)
    src_file = os.path.join(here, ".constants.json")
    with open(src_file) as src:
        constants = json.load(src)
        __author__ = constants['__author__']
        __author_email__ = constants["__author_email__"]
        __license__ = constants["__license__"]
        __maintainer_email__ = constants["__maintainer_email__"]
        __url__ = constants["__url__"]
        __version__ = constants["__version__"]
except IOError:
    # packaged
    pass

cx_Freeze openpyxl未将数据导出到.xlsx文件
