undefined function error

[JonWayn]

I there a switch that I can pass to 'scrapy crawl SpiderName -o ExportFilePath' that will force an overwrite if the file previously existed?

G:\div_code\scrapy_stuff
λ scrapy commands --help
Usage
=====
  scrapy commands

Options
=======
  -h, --help            show this help message and exit
  -a NAME=VALUE         set spider argument (may be repeated)
  -o FILE, --output FILE
                        append scraped items to the end of FILE (use - for stdout)
  -O FILE, --overwrite-output FILE
                        dump scraped items into FILE, overwriting any existing file
  -t FORMAT, --output-format FORMAT
                        format to use for dumping items

Global Options
--------------
  --logfile FILE        log file. if omitted stderr will be used
  -L LEVEL, --loglevel LEVEL
                        log level (default: DEBUG)
  --nolog               disable logging completely
  --profile FILE        write python cProfile stats to FILE
  --pidfile FILE        write process ID to FILE
  -s NAME=VALUE, --set NAME=VALUE
                        set/override setting (may be repeated)
  --pdb                 enable pdb on failure

So instead of -o pass inn -O.

scrapy crawl SpiderName -O ExportFilePath

Thank you
