UnboundedLocalError

[anark10n]

Hey there,
Running protontricks on a game, or even the gui, produces the following error:

Traceback (most recent call last):
File "/usr/bin/protontricks", line 309, in
steam_lib_dirs = get_steam_lib_dirs(steam_dir)
File "/usr/bin/protontricks", line 222, in get_steam_lib_dirs
with open(folders_vdf_path, "r") as f:
UnboundLocalError: local variable 'folders_vdf_path' referenced before assignment`

Any ideas on how to resolve this?

Looking at the code it seems an "else" block is missing, so the error is triggered later inside the try block:

    # Try finding Steam library folders using libraryfolders.vdf in Steam root
    if os.path.isdir(os.path.join(steam_dir, "steamapps")):
        folders_vdf_path = os.path.join(
            steam_dir, "steamapps", "libraryfolders.vdf")
    elif os.path.isdir(os.path.join(steam_dir, "SteamApps")):
         folders_vdf_path = os.path.join(
            steam_dir, "SteamApps", "libraryfolders.vdf")
    try:
        with open(folders_vdf_path, "r") as f:
            library_folders = parse_library_folders(f.read())
    except OSError:
        # libraryfolders.vdf doesn't exist; maybe no Steam library folders
        # are set?
        library_folders = []

I got the error because my steamapps folder was not inside steam folder - I configured in "Settings -> Downloads -> Library Folders" to point to other disk:

My lazy solution was to unify back steamapps to steam folder and the script executed well. Maybe creating symlinks would work too but I haven't tested it. Would be nice if protontricks support non default folders or at least trigger a proper error if the default folders are not found.
