Start script in QProcess?

[Mihaill]

Hi!
I have script:

cd C:/PythonProjects/MibToJson & python C:/PythonProjects/MibToJson/mibToJson.py

How I can start this script in QProcess?
This not work:

m_process.start("cd C:/PythonProjects/MibToJson & python C:/PythonProjects/MibToJson/mibToJson.py")

[JonB]

@Mihaill

m_process.start("cmd", [ "/c", "cd C:/PythonProjects/MibToJson & python C:/PythonProjects/MibToJson/mibToJson.py" ])

Or

m_process.setWorkingDirectory("C:/PythonProjects/MibToJson")
m_process.start("python", ["C:/PythonProjects/MibToJson/mibToJson.py"])

[Mihaill]

@JonB If I do this

m_process.execute("cmd",  { "/c", "python C:/PythonProjects/MibToJson/mibToJson.py"} );

Then I get error:

Python was not found

But in console cmd this script worked.
And if doing this:

m_process.start("python", {"C:/PythonProjects/MibToJson/mibToJson.py"});

Then ,y code in script not creadet file.

@Mihaill said in Start script in QProcess?:

Python was not found

Then use absolute path to python.exe ...

[Mihaill]

@jsulm I use absolute path, but it not help me

@Mihaill said in Start script in QProcess?:

but it not help me

And what is the problem now?

[Mihaill]

@jsulm My python script not work and not create file.
It is to cant create file

m_process.start("C:/PythonProjectsMibToJson/venv/Scripts/python.exe", {  "C:/PythonProjects/MibToJson/mibToJson.py"});

@Mihaill
Does your python.exe accept C:/PythonProjects/MibToJson/mibToJson.py on the command line with those forward slashes? I don't know, if the python.exe runs but something goes wrong with the path passed in I would make that a native path with backslashes. (The same would also apply in your attempt with cmd /c ... earlier.)

Please try to think of others when phrasing your questions or answering.

My python script not work and not create file.

It is to cant create file

What is this about? Create what? You know that we don't know what your script might or might not do, we don't know what "doesn't work" means to you. If you know it tries to create a file from the command line argument why don't you tell us? Otherwise we have no idea what you are talking about.

@JonB I install in OS python, in cmd this work

python C:/PythonProjects/MibToJson/mibToJson.py

My script mibToJson.py must create file, using absolute path. Script not need arguments.
And it's work in cmd, but not work in QProcess

@Mihaill Please add error handling (should be standard in properly written applications):
https://doc.qt.io/qt-6/qprocess.html#errorOccurred
https://doc.qt.io/qt-6/qprocess.html#readAllStandardError

@jsulm I get error:

"Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases.\r\n"

@Mihaill
So you have your answer. Presumably whatever python.exe you have somewhere is not on your PATH.

And it's work in cmd, but not work in QProcess

Then are their PATHs different? Try specifying the full path to python executable as QProcess command.

[jsulm]

@Mihaill So, is this patch actually valid: C:/PythonProjectsMibToJson/venv/Scripts/python.exe
What happens if you enter and execute it in cmd.exe?

[Mihaill]

@jsulm I'm restart computer and it's help me.
