Python打包的.exe在无Python机器运行异常，抛wmi.py错误求助

问题背景 #

• 开发Windows平台可反复调用的.exe工具，用于终止运行超时（卡顿）的指定进程，需传入3个命令行参数：超时分钟数、进程所有者名称、进程全名
• 开发环境：Python 3.11 + VS Code，依赖wmi库获取进程信息，通过PyInstaller打包为单文件.exe
• 本地测试（含Python环境）运行正常，但无Python环境的同事机器上出现两类问题：
  1. 传入正确参数后，程序运行后无输出、无操作、无异常退出
  2. 取消进程打印注释后，机器会列出部分进程，随后程序终止或抛出异常，未执行目标进程终止逻辑

import sys

from datetime import datetime
from datetime import timedelta

# Controll and taking arguments, if they are wrong or missing, the program ends

            print(f'Closing process with ID {process.ProcessId} and name {process.Name} run by {process.GetOwner()[2]}, that was running for {round(minutes,4)} minutes.')
            process.Terminate() # Shout down the process

打包命令 #

pyinstaller --onefile ShutDownProcess.py

解决方案建议 #

• 捕获WMI操作异常：遍历进程时，部分系统核心进程无法获取所有者信息或执行终止操作，会触发未处理异常导致程序崩溃。需在循环内部添加异常捕获逻辑，跳过异常进程继续执行：

  for process in c.Win32_Process():
      try:
          if (process.Name == in_process_name) and (in_user_name in process.GetOwner()):
              created = process.CreationDate.split('.')[0]
              how_long_dt = datetime.now() - datetime.strptime(created, '%Y%m%d%H%M%S')
              minutes = how_long_dt.total_seconds()/60
              if minutes>in_num_of_minutes:
                  print(f'Closing process with ID {process.ProcessId} and name {process.Name} run by {process.GetOwner()[2]}, that was running for {round(minutes,4)} minutes.')
                  process.Terminate()
      except (wmi.x_wmi, pywintypes.com_error):
          continue
  

• 优化进程查询逻辑：避免遍历所有进程，直接通过WMI条件查询过滤目标进程，减少不必要的COM调用，降低异常概率：

  # 替换原遍历逻辑，直接查询指定名称的进程
  target_processes = c.Win32_Process(Name=in_process_name)
  for process in target_processes:
      # 后续逻辑同上（需加异常捕获）
  

• 调整PyInstaller打包参数：单文件打包可能导致WMI依赖的COM组件加载异常，尝试添加隐藏导入参数或改用多文件打包：

  # 添加隐藏依赖打包
  pyinstaller --onefile --hidden-import wmi --hidden-import pywintypes ShutDownProcess.py
  # 或多文件打包（兼容性更好）
  pyinstaller --onedir ShutDownProcess.py
  

• 改用psutil库替代wmi：psutil库兼容性更强，跨平台且打包时问题更少，替换核心逻辑示例：
  1. 安装依赖：pip install psutil
  2. 核心代码替换：

     import sys
     import psutil
     from datetime import datetime
     
     # 参数处理逻辑不变...
     
     for proc in psutil.process_iter(['pid', 'name', 'create_time', 'username']):
         try:
             proc_info = proc.info
             # 匹配进程名称和所有者（注意格式为DOMAIN\USER或.\USER）
             if proc_info['name'] == in_process_name and (in_user_name in proc_info['username']):
                 create_time = datetime.fromtimestamp(proc_info['create_time'])
                 minutes = (datetime.now() - create_time).total_seconds()/60
                 if minutes > in_num_of_minutes:
                     print(f'Closing process with ID {proc_info["pid"]} and name {proc_info["name"]} run by {proc_info["username"]}, that was running for {round(minutes,4)} minutes.')
                     proc.terminate()
         except (psutil.NoSuchProcess, psutil.AccessDenied, psutil.ZombieProcess):
             # 跳过无法访问的进程
             continue
     

• 权限适配：确保同事以管理员权限运行.exe，部分系统进程或高权限进程需要管理员权限才能查询或终止。
