[Python][cx-freeze] 导入错误：无法导入名称 'ExcelFormulaParser'

Question

Hi I encounter an issue when running cx-freeze on a piece of python code. It always threw error message when I click the executable file generated by cx-freeze. Anyone can help? - Python 3.6.1 used.

I also ran the cx-freeze on another piece of python code and it worked well.

Error message is as below:

Source Code in the py file:

import xlwt
import os
import FileDirectory_1


def walk_dir(dir):
    rowindex = 1
    for root, dirs, files in os.walk(dir):
        for f in files:
            if "jpg" in f:
                table.write(rowindex,0, root)
                table.write(rowindex,1, f)
                # print(os.path.join(root,f))
                rowindex += 1


dir = FileDirectory_1.DIR;
excelName = "imageRename.xls"

# =======Excel Style============
style = xlwt.XFStyle()
font = xlwt.Font()
font.name = "Arial"
font.bold = True
style.font = font
# ==============================


file = xlwt.Workbook()
table = file.add_sheet("ImageRename", cell_overwrite_ok=True)
table.write(0, 0, "Old File Path", style)
table.write(0, 1, "Old Image Name", style)
table.write(0, 2, "New Image Name", style)

walk_dir(dir)

file.save(os.path.join(dir, excelName))
print(excelName, " has been generated.")

Answer 1

Found the issue. I checked the files in the /lib/xlwt folder which was generated by cx-freeze and found "ExcelFormulaParser.pyc" and "ExcelFormulaLexer.pyc" files are somehow missing. After adding back the "ExcelFormulaParser.py" and "ExcelFormulaLexer.py" files the issue was resolved. These two files were copied from my own xlwt files from the site package to the build folder.

Answer 2

Actually there isn't any need to copy files. Simply add xlwt as a package dependency in the cx-freeze setup.py file.

eg:

build_exe_options = {"packages": [...your packages.....,  "xlwt"]
                    ...............
                    }

I had the same issue and this will fix it.
