Description

It seems that the example does not work

I'm using Python 3.11.4

[rodja]

It works fine for me (Mac with Python 3.11). What OS are you on? And is there any console log output?

What do you see if you run python3 hello.py in the console?

The result is same.

We use python3 in the run_command calls. But you use simply python. Is python3 working for you? Otherwise you need to change the example and remove the 3.

I change python3 to python ,it works

ui.button("python hello.py", on_click=lambda: run_command("python hello.py")).props(
    "no-caps"
)
ui.button("python slow.py", on_click=lambda: run_command("python slow.py")).props(
    "no-caps"
)

That's great. It seems we can not rely on the existence of python3 command. Maybe we need to probe for the right command at startup? Or take the python bin with which the app has been started?

I just ran these examples to see how it looks , and haven't looked throuth its code, this kind of bug is not actually a bug

[rodja]

True. But it is very inconvenient. I would love to see it fixed.

I'd vote for leaving it as it is. It is just an example and a look into the code would have unveiled the issue.
It is strange though, that the system didn't yield an error message shown in the dialog.
Anyway, that's why I asked for the output of python3 hello.py (which hasn't been answered).

[v479038280]

I'm using python3.11.4,but I didnot install the python2,so I didn't need to use python3,I didn't notice that this is why it didn't work,

@rodja What about ./hello.py? This could be more stable. But we would need to make hello.py and slow.py executable.

@v479038280 Could you check if this works on your machine? The code would look like this:

ui.button('./hello.py', on_click=lambda: run_command('./hello.py')).props('no-caps')
ui.button('./slow.py', on_click=lambda: run_command('./slow.py')).props('no-caps')
with ui.row().classes('items-center'):
    ui.button('./hello.py "<message>"', on_click=lambda: run_command(f'./hello.py "{message.value}"')).props('no-caps')
    message = ui.input('message', value='NiceGUI')

Here is the result

and the console output. not a valid Win32 application (不是有效的 Win32 应用程序) I'm using WIN10 64 PROFESSIONAL
