how to let the log only log ERROR level information

[shyandsy]

I tried lots of way to use the ERROR level, but still all information was wrote into log file

python 3.5 + scrapy 1.2

dmoz_spider.py

configure_logging(install_root_handler=False)
logging.basicConfig(filename='log.txt', format='%(levelname)s: %(message)s', level=logging.ERROR)

settings.py

...................
LOG_LEVEL = "ERROR"

@Jack-Kingdom , @bmetge , @shyandsy ,
I think configure_logging(install_root_handler=False) is what is messing with the configuration.
In #2149 (comment) I removed that line from the docs example, and I was able to have ERROR level with a standalone script using CrawlerRunner.

@shyandsy please see my answer in #2149. I believe this issue can be closed as a clone of that.
