大家好，我遇到了一个棘手的问题，想请教下各位：

我在Python 3.10 64位环境下用PyInstaller打包了一个Windows应用，直接运行PyInstaller生成的dist目录里的exe文件完全正常，但用Inno Setup把这个打包好的程序做成安装包后，安装完成启动程序就报错了，错误提示如下：

Failed to load Python DLL
'C:\Program Files\server.manager_internal\python310.dll'
LoadLibrary: The specified module could not be found.

我特意去安装目录检查过，_internal目录确实存在，而且python310.dll也明确在这个目录里，实在搞不懂为什么经过Inno打包安装后就找不到这个文件了...

我的环境信息 #

• Python版本：3.10.10（64位）
• 操作系统：Windows 10/11 64位
• 打包工具：PyInstaller（使用spec脚本打包）、Inno Setup（向导生成脚本）

我使用的打包配置与命令 #

1. PyInstaller的spec脚本 #

import os
from pathlib import Path

block_cipher = None

BASE_DIR = Path(os.getcwd()).resolve()

a = Analysis(
    ['main.py'],
    pathex=[str(BASE_DIR)],
    binaries=[],
    datas=[
        (str(BASE_DIR / 'serverfile'), 'serverfile'),
    ],
    hiddenimports=[],
    hookspath=[],
    hooksconfig={},
    runtime_hooks=[],
    excludes=[],
    win_no_prefer_redirects=False,
    win_private_assemblies=False,
    cipher=block_cipher,
    noarchive=False,
)

pyz = PYZ(a.pure, a.zipped_data, cipher=block_cipher)

exe = EXE(
    pyz,
    a.scripts,
    [],
    exclude_binaries=True,
    name='server.manager',
    debug=False,
    bootloader_ignore_signals=False,
    strip=False,
    upx=True,
    console=False,
)

coll = COLLECT(
    exe,
    a.binaries,
    a.zipfiles,
    a.datas,
    strip=False,
    upx=True,
    upx_exclude=[],
    name='server.manager',
)

2. Inno Setup的安装脚本 #

我已经尝试过的解决方法 #

1. 手动把python310.dll复制到安装目录的多个位置（比如和exe同目录），问题依旧
2. 清理PyInstaller的缓存后重新打包，再用Inno生成安装包，还是报错
3. 右键以管理员身份运行安装后的程序，没有任何改善

我的疑问 #

为什么直接运行PyInstaller生成的程序完全正常，经过Inno Setup打包安装后就会出现加载python310.dll失败的情况？有没有什么可行的解决办法呢？麻烦各位帮忙看看，谢谢！
