Python OSError: [WinError 193] %1 不是有效的 Win32 应用程序

OSError: [WinError 193] %1 is not a valid Win32 application

提问by Caxton

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].

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]。

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

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

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。

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

错误很明显。该文件hello.py不是可执行文件。您需要指定可执行文件：

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

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

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：

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

Python installers usually register .py files with the system. If you run the shell explicitly, it works:

Python 安装程序通常向系统注册 .py 文件。如果您显式运行 shell，它会起作用：

import subprocess
subprocess.call(['hello.py', 'htmlfilename.htm'], shell=True)
# --- or ----
subprocess.call('hello.py htmlfilename.htm', shell=True)

You can check your file associations on the command line with

您可以在命令行上检查您的文件关联

C:\>assoc .py
.py=Python.File

C:\>ftype Python.File
Python.File="C:\Python27\python.exe" "%1" %*

I got the same error while I forgot to use shell=Truein the subprocess.call.

当我忘记shell=True在subprocess.call.

subprocess.call('python modify_depth_images.py', shell=True)

Running External Command

To run an external command without interacting with it, such as one would do with os.system(), Use the call() function.

import subprocess

Simple command subprocess.call(['ls', '-1'], shell=True)

运行外部命令

要在不与其交互的情况下运行外部命令，例如使用 os.system()，请使用 call() 函数。

导入子流程

简单命令 subprocess.call(['ls', '-1'], shell=True)

OSError: [WinError 193] %1 不是有效的 Win32 应用程序

This error is most probably due to this line import subprocess

此错误很可能是由于此行导入子进程

I had the same issue and had solved it by uninstalling and reinstalling python and anaconda then i used jupyter and wrote pip install numpythis gave me the whole path where it was getting my site-packages from i deleted my site-packages folder and then the error dissappeared. Actually because i had 2 folders for site-packages one with anaconda and other somewhere in app data(which had some issues in it), since i deleted that site-package folder then it automatically started taking my libraries from site-package folder which was with anaconda hence the problem was solved.

我遇到了同样的问题，并通过卸载并重新安装 python 和 anaconda 解决了它，然后我使用了 jupyter 并编写了pip install numpy这给了我从我删除站点包文件夹中获取站点包的完整路径，然后错误消失了。实际上，因为我有 2 个站点包文件夹，一个是 anaconda，另一个是应用程序数据中的某个位置（其中存在一些问题），因为我删除了该站点包文件夹，然后它会自动开始从站点包文件夹中获取我的库有了anaconda，问题就解决了。

Uninstalling numpyfrom command line / terminal through pipfixed the error for me:

numpy通过命令行/终端卸载pip为我修复了错误：

pip uninstall numpy

pip uninstall numpy

All above solution are logical and I think covers the root cause, but for me, none of the above worked. Hence putting it here as may be helpful for others.

以上所有解决方案都是合乎逻辑的，我认为涵盖了根本原因，但对我来说，以上都没有奏效。因此把它放在这里可能对其他人有帮助。

My environmentwas messed up. As you can see from the traceback, there are two python environments involved here:

我的environment被搞砸了。从回溯中可以看出，这里涉及到两个 python 环境：

1. C:\Users\example\AppData\Roaming\Python\Python37
2. C:\Users\example\Anaconda3

1. C:\Users\example\AppData\Roaming\Python\Python37
2. C:\Users\example\Anaconda3

I cleaned up the path and just deleted all the files from C:\Users\example\AppData\Roaming\Python\Python37.

我清理了路径并从C:\Users\example\AppData\Roaming\Python\Python37.

Then it worked like the charm.

然后它就像魅力一样工作。

I hope others may find this helpful.
