Problem importing Apache logs

I used this command for importing Apache log files but I am getting the following error message

$ python /home/nube/webapps/piwik/misc/log-analytics/  --url= access_log.processed.3 --idsite=1 --enable-reverse-dns --enable-http-errors --enable-http-redirects  --enable-static --enable-bots

    piwik.numbers = {

        patternPercent: "#,##0%",
        patternCurrency: "¤#,##0.00",

        symbolMinus: "-",

I think you should only specify Piwik base URL
