mpremote vscode extension is not calling the module on windows

[nexafs-git]

Hello Dave,

after successfully installing and using your mpremote extension on linux the exact same procedure on a windows system yields the following error during vscode startup : 'mpremote is not installed or could not be run as a Python module'. Other commands will not launch either, and no serial devices are found in the respective editor tab.

But for the windows OS the COM device is connected and the module is usable via a terminal with the 'mpremote' command to connect to a ESP32 device running micropython.

In an earlier post you described the function to determine how to call the module:

export function getMPRemoteName() {
let mpremote = 'python3 -m mpremote';
switch (process.platform) {
case 'win32': // win32 is returned for 64-bit OS as well
mpremote = 'py.exe -m mpremote';
break;
case 'linux':
case 'darwin':
mpremote = 'mpremote';
break;
}
console.debug('Calling mpremote as:', mpremote);
return mpremote;

That doesn't seem to work, and for this reason I already have overwritten the starter command with 'mpremote' in the vscode/mpremote settings file, but this did not work either.
Is there another way letting the extension find the module?

Thanks!

Try running py.exe -m mpremote --help at the VS Code command prompt. Does that work? Also, if you're using a Python virtual environment, that can throw it off. There's an extension setting to skip the check in that case.

Thanks for the quick reply!

The py.exe -m command structure does not exist on my system, maybe due to the anaconda installation.
But the standard 'python' or 'python -m' command launches the interpreter version 3.13.5 and there is also no venv running.

The 'python -m mpremote' is even working at the VS Code prompt, but it seams as if the extension does not link to it, even if I fill it into the extension's 'Mpremote: Command' Setting.

If I skip the startup check the one error is gone. However with the next action e.g. scanning for devices another error is thrown: Error running command mpremote.refreshSerialPorts: command 'mpremote.refreshSerialPorts' not found. This is likely caused by the extension that contributes mpremote.refreshSerialPorts.

When I installed Python, it was with the installer from python.org. It installs py.exe in my system path. You mentioned anaconda. Guessing that it's not installing py.exe. If you're using a custom command in the options, make sure that command runs successfully in the VS Code terminal window.

You might need to give a full path to python.exe.

The full path name did it... Thank you, Dave!

Also generally for this nice and convenient extension!
