"IndentationError: Unexpected Indent" when running scrapy, blank csv file

[TheSeedMan]

Hello, when running scrapy using default arguments, I am prompted with an Indentation Error, scrapy outputs the task is completed, and I'm left with a blank csv file. Does anyone know how I can troubleshoot this issue?

_scrapy crawl fb -a email="@gmail.com" -a password="pwd" -a page="DonaldTrump" -a lang="en" -o Trump.csv_

if you downgrade scrapy framework to version 1.5.0 it works fine

[Di-ref]

Try removing the commented lines in fbcrawl.py line 141 in the body of the parse_page() function
if that does not work try removing the comments from the body of the parse_page() function in these files :

• fbcrawl.py
• comments.py
• events.py
• profiles.py

it's a bug in the Scraper library mentioned in this issue here
