UnboundLocalError: local variable 'logFile' referenced before assignment

[gs-opencos-zte]

code in run_setup.py：main() is:
def main():
    options = ""

    try:
        # Load Plugins
        loadPlugins()
        initPluginsConfig()

        optParser = initCmdLineParser()

        # Do the actual command line parsing
        # Try/Except are here to catch the silly sys.exit(0) when calling rhevm-setup --help
        (options, args) = optParser.parse_args()
        if options.options:
            printOptions()
            raise SystemExit

        # Initialize logging
        logFile = initLogging(options.debug) //logFile defined here is too late

        # Parse parameters
        runConfiguration = True
        confFile = None

        ....

    except FlagValidationError as ex:
        optParser.error(str(ex))
    except Exception as e:
        logging.error(traceback.format_exc())
        print("\n" + utils.color_text("ERROR : " + str(e), 'red'))
        print(output_messages.ERR_CHECK_LOG_FILE_FOR_MORE_INFO % (logFile))
        sys.exit(1)

    finally:
        remove_remote_var_dirs(options, controller.CONF, controller.MESSAGES)
        remove_temp_files()

when some exception raised at optParser.parse_args() or before, "UnboundLocalError: local variable 'logFile' referenced before assignment" will be found. i think it logFile should be defined before loadPlugins().

    Avoid error if logFile is not defined

    If there is an error initializing a plugin or checking the command-line
    arguments, we may use the logFile variable without having
    initialized it, which causes an exception.

    In those cases there will be no log file, so let's catch the
    exception and ignore it if it happens.
