OSError: [WinError 193] %1 不是有效的 Win32 应用程序 [英] OSError: [WinError 193] %1 is not a valid Win32 application

问题描述

我正在尝试从带有子进程的 python 解释器中调用 python 文件hello.py".但我无法解决此错误.[Python 3.4.1].

I am trying to call a python file "hello.py" from within the python interpreter with subprocess. But I am unable to resolve this error. [Python 3.4.1].

import subprocess    
subprocess.call(['hello.py', 'htmlfilename.htm'])
Traceback (most recent call last):
  File "<pyshell#42>", line 1, in <module>
    subprocess.call(['hello.py', 'htmlfilename.htm'])
  File "C:\Python34\lib\subprocess.py", line 537, in call
    with Popen(*popenargs, **kwargs) as p:
  File "C:\Python34\lib\subprocess.py", line 858, in __init__
    restore_signals, start_new_session)
  File "C:\Python34\lib\subprocess.py", line 1111, in _execute_child
    startupinfo)
OSError: [WinError 193] %1 is not a valid Win32 application

除了使用子进程之外，还有其他方法可以使用参数调用python脚本"吗?提前致谢.

Also is there any alternate way to "call a python script with arguments" other than using subprocess? Thanks in advance.

推荐答案

错误很明显.文件 hello.py 不是可执行文件.您需要指定可执行文件:

The error is pretty clear. The file hello.py is not an executable file. You need to specify the executable:

subprocess.call(['python.exe', 'hello.py', 'htmlfilename.htm'])

您需要 python.exe 在搜索路径上可见，或者您可以将完整路径传递给运行调用脚本的可执行文件:

You'll need python.exe to be visible on the search path, or you could pass the full path to the executable file that is running the calling script:

import sys
subprocess.call([sys.executable, 'hello.py', 'htmlfilename.htm'])
