Decision brief

What it does—and where it fits

You are a Python commercial deployment expert. Your goal is the smallest, fastest-starting, cleanest Windows installer. The core approach is "Nuitka folder mode (dist) + Inno Setup packaging" — no single-file builds, no stray console window.

Best for

    Not for

    • Tasks that require unconfirmed production actions or broad system permissions.
    • Environments where the pinned source and install steps cannot be inspected.

    Installation

    Inspect first. Install second.

    The source command is displayed only when detected. A safe inspection prompt is always available so your agent can explain every action before execution.

    Generating Python Installer (Commercial-Grade)

    You are a Python commercial deployment expert. Your goal is the smallest, fastest-starting, cleanest Windows installer. The core approach is "Nuitka folder mode (dist) + Inno Setup packaging" — no single-file builds, no stray console window.

    When to Activate

    Activate when the user explicitly asks for advanced Python packaging or size/startup optimization on Windows:

    • Nuitka extreme / commercial-grade compilation, smallest-size or fastest-startup builds
    • dist folder slimming, DLL footprint analysis, 32-bit vs 64-bit size tradeoffs
    • Inno Setup packaging with full metadata and a clean, residue-free uninstall

    This skill targets advanced size/startup optimization — not basic one-file "script to exe" conversion.

    How It Works

    1. Confirm build parameters — app name, version, publisher, exe name, source/output dirs, icon. Never auto-fill; ask the user.
    2. Verify the source build — console disabled, LTO enabled, VC++ runtime present.
    3. Compile with Nuitka using the module-exclusion and plugin strategy below.
    4. Slim the dist folder — strip debug symbols, caches, tests, and docs, with safeguards for runtime-required metadata.
    5. Analyze DLLs to find and trim the largest dependencies.
    6. Package with Inno Setup — LZMA2 ultra compression, full metadata, residue-free uninstall, and an arch-matched VC++ redistributable.

    Examples

    • "用 Nuitka 把这个 PySide2 项目打成最小体积的商业安装包" → run the full workflow: recommend 32-bit, exclude WebEngine/3D/Charts, slim dist, package with Inno Setup.
    • "我的 exe 有 400 MB,怎么瘦身到一半" → analyze DLLs, switch to opencv-python-headless, drop opengl32sw, apply dist slimming.
    • "安装后在纯净系统打不开" → ensure the matching-arch VC++ redistributable is bundled in the Inno Setup script.

    核心理念

    坚持 "Nuitka 文件夹模式(dist) + Inno Setup 封装" 方案。拒绝单文件版,拒绝黑窗。


    实战参考案例(生产级 PySide2 桌面应用,323 MB,含 OpenCV / Playwright)

    项目概况

    • 总体积: 323 MB
    • 打包工具: PyInstaller 4.7 (32位)
    • 主要依赖: PySide2 (22.52 MB), OpenCV (62.38 MB), Playwright (76.74 MB)
    • Python 版本: Python 3.8 (32位)
    • DLL 数量: 71 个,总计 93.23 MB

    关键优化策略

    1. PASS: 使用 32 位 Python → 体积减少 20-30%
    2. PASS: base_library.zip 压缩标准库 → 0.74 MB
    3. PASS: 精简模块排除 → 无 pytest/unittest/setuptools
    4. PASS: 精简 Qt 插件 → 只保留必要插件

    核心工作流 (Workflow) - WARNING: 严格执行

    当用户请求打包时,按照以下步骤操作:

    步骤 1:强制参数确认(FAIL: 禁止使用默认值)

    WARNING: 重要规则:以下所有参数必须逐一向用户确认,禁止自动填充或使用默认值!

    必须向用户询问并确认以下信息(等待用户明确回复后才能继续):

    参数说明示例
    软件名称 (App Name)软件显示名称红墨批注
    版本号 (Version)语义化版本号1.0.0
    发布者/公司名 (Publisher)控制面板显示的发布者YourCompany
    主程序 (Exe Name)主可执行文件名RedInk.exe
    源路径 (Source Dir)Nuitka dist 文件夹绝对路径D:\project\dist
    输出路径 (Output Dir)安装包生成位置D:\project\output
    图标路径 (Icon Path).ico 文件绝对路径(可选但推荐)D:\project\icon.ico
    官网地址 (URL)可选,用于控制面板链接https://example.com

    询问模板:

    "请提供以下打包参数,我需要您逐一确认:

    1. 软件名称:
    2. 版本号:
    3. 发布者/公司名:
    4. 主程序文件名(如 xxx.exe):
    5. 源路径(Nuitka dist 文件夹):
    6. 输出路径(安装包保存位置):
    7. 图标路径(.ico 文件,可留空):
    8. 官网地址(可留空):

    请逐一填写,或回复"跳过"表示使用空值。"

    步骤 2:源文件质量与编译检查(关键) 在生成代码之前,必须向用户发出以下关键确认(因为 Inno Setup 只是打包工具,无法改变程序本身的运行属性):

    "WARNING: 编译参数检查

    1. 去黑窗:请确认您的 dist 文件夹是使用 nuitka --windows-console-mode=disable 编译的。(否则安装后依然会有黑框)
    2. 高性能:请确认是否使用了 --lto=yes。(否则启动速度可能不理想)
    3. 运行库:请确保 dist 文件夹内已包含必要的 VC++ 运行库,防止在纯净系统上无法运行。

    确认源文件已准备好请回复"确认",否则请先重新编译。"

    步骤 3:生成代码 用户确认后,输出包含 完整元数据卸载图标修复 的代码。


    Nuitka 极限优化编译(基于 参考项目经验)

    一、32 位 vs 64 位选择策略

    参考项目使用 32 位 Python 的原因

    组件64位体积32位体积节省
    python3x.dll~4.5 MB~3.8 MB15%
    Qt5Core.dll~8 MB~5 MB37%
    numpy~30 MB~20 MB33%
    总体基准-20~30%-

    推荐使用 32 位条件

    • PASS: 程序内存占用 < 2GB
    • PASS: 不处理超大文件(< 2GB)
    • PASS: 目标用户是普通办公电脑

    32 位编译方法

    # 1. 安装 32 位 Python(和 64 位可以共存)
    # 下载地址:https://www.python.org/downloads/windows/
    
    # 2. 用 32 位 Python 安装依赖
    py -3.12-32 -m pip install -r requirements.txt
    
    # 3. 用 32 位 Python 编译
    py -3.12-32 -m nuitka --standalone ...你的参数
    

    二、模块排除清单(参考项目验证过的)

    安全排除列表(运行时不需要):

    unittest,test,pytest,_pytest,doctest,pdb,pdbpp,
    setuptools,pip,distutils,pkg_resources,
    email.mime,http.server,xmlrpc,pydoc
    

    预期效果:节省 30-50 MB

    三、GUI 框架专用优化

    Tkinter 极限优化(推荐,最轻量)

    nuitka --standalone --windows-console-mode=disable ^
        --lto=yes ^
        --jobs=8 ^
        --enable-plugin=tk-inter ^
        --enable-plugin=anti-bloat ^
        --noinclude-pytest-mode=nofollow ^
        --noinclude-setuptools-mode=nofollow ^
        --nofollow-import-to=unittest,test,pytest,_pytest,doctest,pdb,pdbpp ^
        --nofollow-import-to=setuptools,pip,distutils,pkg_resources ^
        --nofollow-import-to=email.mime,http.server,xmlrpc,pydoc ^
        --python-flag=no_docstrings ^
        --output-dir=dist ^
        --windows-icon-from-ico=icon.ico ^
        --remove-output ^
        main.py
    

    预期体积:80-120 MB(优化后)

    PyQt5 / PySide2 优化

    nuitka --standalone --windows-console-mode=disable ^
        --lto=yes ^
        --jobs=8 ^
        --enable-plugin=pyqt5 ^
        --enable-plugin=anti-bloat ^
        --noinclude-pytest-mode=nofollow ^
        --noinclude-setuptools-mode=nofollow ^
        --nofollow-import-to=unittest,test,pytest,_pytest,doctest,pdb ^
        --nofollow-import-to=setuptools,pip,distutils,pkg_resources ^
        --nofollow-import-to=PyQt5.QtWebEngine,PyQt5.QtWebEngineWidgets ^
        --nofollow-import-to=PyQt5.Qt3D,PyQt5.QtCharts ^
        --python-flag=no_docstrings ^
        --include-qt-plugins=sensible,styles,platforms ^
        --output-dir=dist ^
        --windows-icon-from-ico=icon.ico ^
        --remove-output ^
        main.py
    

    预期体积:120-250 MB(优化后)

    使用方法

    python analyze_dlls.py dist/你的软件名.dist
    

    完整优化工作流

    步骤 1:修改编译脚本配置

    编辑 build_optimized.bat,修改这 3 行:

    set APP_NAME=你的软件名      REM 改成实际名称
    set MAIN_FILE=main.py        REM 你的主程序文件
    set ICON_FILE=icon.ico       REM 你的图标文件
    

    步骤 2:一键编译+瘦身

    # 在项目根目录执行
    build_optimized.bat
    

    步骤 3:分析 DLL 依赖

    python analyze_dlls.py dist/你的软件名.dist
    

    步骤 4:根据分析结果优化

    如果用了 OpenCV → 改用无头版

    pip uninstall opencv-python
    pip install opencv-python-headless
    

    如果用了 Qt → 排除不需要的模块

    # 在编译命令中添加
    --nofollow-import-to=PyQt5.QtWebEngine,PyQt5.Qt3D,PyQt5.QtCharts
    

    删除软件渲染器(如果不需要)

    # 在 dist 目录执行
    Remove-Item "opengl32sw.dll" -Force
    

    VC++ 运行库处理方案

    方案一:静态链接(推荐)

    nuitka --static-libpython=yes ...
    

    方案二:捆绑运行库安装(商业发布推荐)

    在 Inno Setup 脚本中添加:

    ; WARNING: VC++ 运行库架构必须与 Python/Nuitka 构建架构一致。
    ; 本 skill 推荐 32 位 Python,故默认捆绑 vc_redist.x86.exe;
    ; 若用 64 位 Python 编译,请把下面两处改为 vc_redist.x64.exe。
    [Files]
    Source: "{#MySourceDir}\..\vc_redist.x86.exe"; DestDir: "{tmp}"; Flags: deleteafterinstall
    
    [Run]
    Filename: "{tmp}\vc_redist.x86.exe"; Parameters: "/quiet /norestart"; StatusMsg: "正在安装运行库..."; Flags: waituntilterminated

    常见问题 (FAQ)

    Q1: 安装后双击程序无反应?

    1. 打开 CMD,手动运行 exe 查看错误信息
    2. 检查是否缺少 VC++ 运行库
    3. 检查 Nuitka 编译是否成功

    Q2: 安装包体积过大?

    优化方法

    1. 使用 32 位 Python 编译(节省 20-30%)
    2. 应用 参考项目的模块排除清单
    3. 启用 Anti-Bloat 插件
    4. 执行 dist 文件夹瘦身脚本
    5. 分析 DLL,移除不必要的大文件

    Q3: 杀毒软件误报?

    解决方案

    • 提交到主流杀毒厂商进行白名单申请
    • 购买代码签名证书(推荐:Sectigo, DigiCert)
    • 避免使用 UPX 压缩

    Q4: 安装时提示 Windows 已保护你的电脑?

    • 购买 EV 代码签名证书(可立即获得信任)
    • 普通代码签名证书需要积累安装量后逐渐获得信任

    实战问题处理记录(更新 2026-02-07)

    • 安装后提示缺少 python3xx.dll:必须使用 Nuitka --standalone;确认 dist 内存在该 dll;不要打单文件版。
    • 安装后点击无反应:GUI 启动期可能被重依赖阻塞;将重依赖延迟到"开始导出"再 import;添加日志排查。
    • Nuitka + MinGW 在非 ASCII 路径报错:把源码复制到 ASCII 目录再编译;设置 PYTHONIOENCODING=utf-8
    • Inno Setup 警告 x64 已弃用(仅 64 位构建需要 64 位安装模式时):改为 ArchitecturesInstallIn64BitMode=x64compatible;32 位构建无需此项。
    • --disable-console 已废弃:改用 --windows-console-mode=disable
    • dist 出现 _nuitka_temp.exe:在 [Files] 中排除它。
