I don't understand how to properly install

[ZeralldMC]

I have this code in my python app:

import os 
import eel
import jinja2
import requests
import json
import subprocess
from portablemc import StartOptions
from portablemc import Start
from portablemc import Context
from portablemc import VersionManifest
from portablemc import Version, VersionError, JvmLoadingError

@eel.expose
def startGame():
    main_dir = "app/user/data"
    work_dir = "app/user/minecraft"

    manifest = VersionManifest()
    ctx = Context(main_dir, work_dir)

    start_opts = StartOptions()
    start_opts.disable_multiplayer = False
    start_opts.username = "niceworld"
    start_opts.resolution = (700, 500)

    version_id = manifest.filter_latest("1.18.1")
    version = Version(ctx, version_id)

    try:
        version.install(jvm=True)
    except VersionError as e:
        print(f"Version '{e.version}' not found.")
    except JvmLoadingError as e:
        print(f"No JVM found for you system.")

    start = Start(version)
    start.prepare(start_opts)
    start.start()

I am using the EEL library to run functions through an HTML shell. Here is the console log on startup:

I really don't understand what the problem is. Excuse me if this seems silly to you, but I'm not very good at it.

The problem here is that your version_id variable is being set to a tuple. This is because the manifest.filter_latest("1.18.1") function returns a tuple (version, alias). So you should use version_id, alias = manifest.filter_latest("1.18.1") instead. The alias variable is a boolean that indicates if the given identifier is an alias or not. By the way for your exemple, it's not that useful to use filter_latest because 1.18.1, unlike snapshot or release, is not an alias.
