python – logger找不到文件

$python3.4 cron_e2e.py -f test_web_events -E ctg-clickstream testbrad

错误：

$python3.4 cron_e2e.py -f test_web_events -E ctg-clickstream testbrad
Traceback (most recent call last):

FileNotFoundError: [Errno 2] No such file or directory: '/Users/bli1/Development/QE/chun-qe-trinity-functional/qe/tests/qe/logs/testbrad_8_21_2015_cron.log'

错误发生在这一行：

log.addHandler(logging.FileHandler(logfile))

不太确定我的代码在哪里不为我创建日志文件

码：

def main(argv):
    "Test"
    exit_code = 0
    global me; me = os.path.basename(argv[0]) # name of this program
    global mydir; mydir = os.path.dirname(os.path.abspath(__file__))
    parser = argparse.ArgumentParser(description=main.__doc__)
    parser.add_argument("-f","--functional_test",metavar="FUNCTEST",dest="functest",help="Type of functional test")
    parser.add_argument("-p","--phase",action="append",metavar="POST|HDFS|HIVE|ALL",dest="phase",help="phase of test to run")
    parser.add_argument("-t","--testfile",metavar="TESTFILE",dest="testfile",default=os.path.join(mydir,"resources/cron.json"),help="file with test commands")
    parser.add_argument("-E","--Event",metavar="EVENTNAME",dest="event_names",help="[repeatable] topic to which to post")
    parser.add_argument("runtag",metavar="RUNTAG",help="run tag for this run")
    args = parser.parse_args(args=argv[1:])  # will exit on parse error
    log = logging.getLogger(me)
    log.setLevel(logging.INFO)
    dt = datetime.datetime.utcnow()
    logfile = "qe/logs/" + (args.runtag + "_{}_{}_{}".format(dt.month,dt.day,dt.year) + "_cron.log")

    pdb.set_trace()
    if isinstance(logfile,str):
        if os.path.exists(logfile):
            os.remove(logfile)
        # logging.FileHandler() returns FileHandler class,the file is opened and used as the stream for logging
        log.addHandler(logging.FileHandler(logfile))
    console = logging.StreamHandler(sys.stderr); console.setLevel(logging.WARNING); log.addHandler(console)
