已经解决，通过在本地重新编译libexpat，并让spec文件中引用

• 首先，需要下载并编译libexpat 2.6.4版本：

# 创建工作目录
mkdir -p ~/expat_build
cd ~/expat_build

# 下载expat 2.6.4源码
wget https://github.com/libexpat/libexpat/releases/download/R_2_6_4/expat-2.6.4.tar.gz
tar -xzf expat-2.6.4.tar.gz
cd expat-2.6.4

# 配置编译选项（指定安装到用户目录下的自定义位置）
./configure --prefix=$HOME/expat_install

# 编译
make -j$(nproc)

# 安装到指定目录
make install

• 修改.spec文件

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

a = Analysis(
    ['your_script.py'],
    pathex=[],
    binaries=[
        ('~/expat_install/lib/libexpat.so.1', '.'),
        ('~/expat_install/lib/libexpat.so.1.10.0', '.')  # 版本号可能会有所不同
    ],
    datas=[],
    hiddenimports=[],
    hookspath=['./hooks'],
    hooksconfig={},
    runtime_hooks=[],
    excludes=[],
    win_no_prefer_redirects=False,
    win_private_assemblies=False,
    cipher=None,
    noarchive=False,
)

pyz = PYZ(a.pure, a.zipped_data, cipher=None)

exe = EXE(...)  # 保持原有配置

coll = COLLECT(...)  # 保持原有配置
