hi
Im trying to execute :
$ python3.4m Facebook-Marketplace-Selenium.py
and Im getting:

File "Facebook-Marketplace-Selenium.py", line 158, in <module> app = App() File "Facebook-Marketplace-Selenium.py", line 18, in __init__ self.driver = webdriver.Firefox() File "/usr/lib/python3.4/site-packages/selenium/webdriver/firefox/webdriver.py", line 157, in __init__ self.service.start() File "/usr/lib/python3.4/site-packages/selenium/webdriver/common/service.py", line 76, in start stdin=PIPE) File "/usr/lib64/python3.4/subprocess.py", line 858, in __init__ restore_signals, start_new_session) File "/usr/lib64/python3.4/subprocess.py", line 1456, in _execute_child raise child_exception_type(errno_num, err_msg) NotADirectoryError: [Errno 20] Not a directory

any idea what Im doing wrong ?
Cheers

@kiwikot you probably just need to specify the folder you're going to send the data to based on what I'm guessing from that error message.

def init(self, email= "", password= "",
path='specify/folderpath/here'):

So how do I go if I want to scrape for new postings only (eg 24 hours)? Also, what is the area this script would be using? I want to be able to search nationwide?

Thanks

Hello, from what i could find, these lines of codes arent defined. how is LOCAL_USED_ITEMS supposed to perform?
db = LOCAL_USED_ITEMS

    db.Facebook_items.insert({ 'Url': url,
                     'Images': images,
                     'Title': title,
                     'Description': description,
                     'Date_Time': date_time,
                     'Location': location,
                     'Price': price,          
                    })

thank you for any help:)

@ohliuw this script just manually scrapes when you run the code, you would need to run it manually daily to capture new posts. I haven't used it in a while but I'm sure there's a way you could automate running the script every 24 hours. Also, the area script covers is dependent on the approximate area from which you're signing in. Sounds like you are looking for more commercialized scraping which is beyond the scope of this project

@osrstaurean that method is simply inserting the parameters for each item scraped into the database. The values for the dictionary created for each item are parsed out via the scrape_item_details function of the script.
