I installed the required packages according to the instruction, but got the following error when trying to run the script. Is there anything else I should setup beside the steps detailed in the installation guide?
Thank you.

EDIT: Mongo has to be installed and started first. In Arch Linux the package is called mongodb. It's a little bit confusing for people who are not familiar with this field, because for instance if you install opencv-python, it will actually install opencv itself and its python binding, which is apparently not the case for pymongo.

Info about the platform I am running: Arch Linux + Python 3.6 + mongodb 3.6.3-1 + firefox 59.

Ok, I have to install mongodb and then start the service.
Now when I run with dumb_site option, it will give the following error

Tried scrape_messages, it started firefox, but seemed to be happening. Then after a while, it produced the following errors:

Is there any specific requirement about the version of Mongo?
Since other python packages were installed from requirement.txt, they have exactly the version as specified, so the remaining uncertainty could only be Mongo and Firefox?

[brewingcode]

Just in case anyone else finds this, I was seeing the exact same thing on macOS as #47 (comment): the scraper would open a Firefox window and just sit for 30 seconds or so, then fail out with selenium.common.exceptions.WebDriverException: Message: Can't load the profile. Profile Dir: /tmp/tmpr0umenb9 If you specified a log_file in the FirefoxBinary constructor, check it for details. .

I was able to quickly fix it by swapping to Chrome instead of Firefox:

$ brew tap homebrew/cask
$ brew cask install chromedriver
$ ./yahoo-groups-backup.py $COMMAND $GROUPNAME --driver=chrome

Note: you install chromedriver but pass --driver=chrome to the Python script.
