# 安装PyInstaller
pip install pyinstaller

# 生成spec文件
pyi-makespec --onefile --windowed --name="文本处理工具" your_script.py

# 编辑生成的spec文件，添加以下内容来减小体积：

修改spec文件：

# -*- mode: python ; coding: utf-8 -*-

block_cipher = None

    hooksconfig={},
    runtime_hooks=[],
    excludes=['matplotlib', 'numpy', 'pandas', 'scipy', 'IPython', 'jupyter'],  # 排除不需要的大包
    win_no_prefer_redirects=False,
    win_private_assemblies=False,
    noarchive=False,

pyx = PYZ(a.pure, a.zipped_data)

exe = EXE(
    pyx,
    a.scripts,
    a.binaries,
