How do you run the game offline?

[RiverRyan3000]

the code is

from portablemc.standard import Version
Version().install().run()

the game is installed so is there anyway to run the game without using install()?
because when i run the code without internet while the game is installed it passes

Hi! There must be a problem with the launcher's API, I'll look at this for the upcoming patch

[mindstorm38]

Problem found! Should be fixed on next release.
Now, if any network error happens while fetching manifest, but the version is already installed, it will work.
