pyinstaller错误:OSError:[WinError 6]句柄无效

问题描述 投票:0回答:2

此文件使用终端命令获取wifi密码

netsh wlan show profiles
我之前使用 pyinstaller 创建了一些 .exe,它们工作得很好。

代码:

import subprocess
import time
import sys
import re

command_output = subprocess.run(["netsh", "wlan", "show", "profiles"], capture_output = True).stdout.decode()

profile_names = (re.findall("All User Profile     : (.*)\r", command_output))

wifi_list = []

if len(profile_names) != 0:
    for name in profile_names:
        wifi_profile = {}
        profile_info = subprocess.run(["netsh", "wlan", "show", "profile", name], capture_output = True).stdout.decode()
        if re.search("Security key           : Absent", profile_info):
            continue
        else:
            wifi_profile["ssid"] = name
            profile_info_pass = subprocess.run(["netsh", "wlan", "show", "profile", name, "key=clear"], capture_output = True).stdout.decode()
            password = re.search("Key Content            : (.*)\r", profile_info_pass)
            if password == None:
                wifi_profile["password"] = None
            else:
                wifi_profile["password"] = password[1]
            wifi_list.append(wifi_profile)

for x in range(len(wifi_list)):
    print(wifi_list[x])

time.sleep(5)
print("No more WiFi Profiles Found")
time.sleep(3)
sys.exit()

这是我运行 .exe 时遇到的错误:

Traceback (most recent call last):
  File "GetWiFiPassWord.py", line 6, in <module>
  File "subprocess.py", line 453, in run
  File "subprocess.py", line 709, in __init__
  File "subprocess.py", line 1006, in _get_handles
OSError: [WinError 6] The handle is invalid
python windows subprocess pyinstaller

这个错误显然是抛出的,因为:

subprocess.py 中的第 1117 行是:

p2cread = _winapi.GetStdHandle(_winapi.STD_INPUT_HANDLE)

服务进程没有与之关联的 STDIN(待定)。

可以通过提供文件或空设备作为

popen
的 stdin 参数来避免此问题。

Python 3.x 中,您可以简单地传递

stdin=subprocess.DEVNULL
。 例如

subprocess.Popen( args=[self.exec_path], stdout=subprocess.PIPE, stderr=subprocess.STDOUT, stdin=subprocess.DEVNULL)

Python 2.x 中,您需要将文件处理程序设置为 null,然后传递 那个打开:

devnull = open(os.devnull, 'wb')
subprocess.Popen( args=[self.exec_path], stdout=subprocess.PIPE, stderr=subprocess.STDOUT, stdin=devnull)  

参考:OSError:(WinError 6)句柄无效


您的问题:

subprocess.run(["netsh", "wlan", "show", "profiles"], capture_output = True, stdin=subprocess.DEVNULL).stdout.decode()

我在使用 pyinstaller 时遇到了同样的问题:

PyInstaller: 4.5.1
Python: 3.9.6
Platform: Windows-10-10.0.19042-SP0

谢谢Behdad Abdollahi Moghadam。我通过将

stdin
stder
添加到
subprocess.check_output

解决了我的问题
subprocess.check_output("C:\Program Files (x86)\xxx.exe", stdin=subprocess.DEVNULL, stderr=subprocess.STDOUT)
