Question

我正在尝试创建一个打开程序的脚本。我有一个命令，我通常在Windows运行中手动运行（Windows Key + R）。

command "C:\Riot Games\League of Legends\RADS\solutions\lol_game_client_sln\releases\0.0.1.54\deploy\League of Legends.exe" "8394" "LoLLauncher.exe" "" "spectator 95.172.65.26:8088 kbbaZXzvdjwL2tHtX7XGaEG17tJQLVBa 945850509 EUN1"

import subprocess
subprocess.call('"C:\Riot Games\League of Legends\RADS\solutions\lol_game_client_sln\releases\0.0.1.53\deploy\League of Legends.exe" "8394" "LoLLauncher.exe" "" "spectator 95.172.65.26:8088 kbbaZXzvdjwL2tHtX7XGaEG17tJQLVBa 945850509 EUN1"')

当我运行时，我收到错误：

Traceback (most recent call last):
  File "C:\Users\Duran\Desktop\helloworld.py", line 2, in <module>
    subprocess.call('"C:\Riot Games\League of Legends\RADS\solutions\lol_game_client_sln\releases\0.0.1.53\deploy\League of Legends.exe" "8394" "LoLLauncher.exe" "" "spectator 95.172.65.26:8088 kbbaZXzvdjwL2tHtX7XGaEG17tJQLVBa 945850509 EUN1"')
  File "C:\Python34\lib\subprocess.py", line 537, in call
    with Popen(*popenargs, **kwargs) as p:

    restore_signals, start_new_session)
  File "C:\Python34\lib\subprocess.py", line 1111, in _execute_child
    startupinfo)
TypeError: must be str without null characters or None, not str

你可能已经看到我对此很新，但如果有人能帮助我，我会非常感激。

"\0"是NUL字符 - ord('\0') == 0。它会在您的问题中导致TypeError。

使用r"\0"获取两个符号：反斜杠加小数零 -
list(map(ord, r'\0')) == [92, 48]。

from subprocess import check_call

check_call([
    r"C:\Riot Games\League of Legends\RADS\solutions\lol_game_client_sln\releases\0.0.1.54\deploy\League of Legends.exe",
    "8394",
    "LoLLauncher.exe",
    "",
    "spectator 95.172.65.26:8088 kbbaZXzvdjwL2tHtX7XGaEG17tJQLVBa 945850509 EUN1"
])

注意：引号内没有引号。

在Windows上运行子进程导致TypeError：必须是没有空字符的str或None，而不是str
