SQL Alchemy 1.4 not supported, throws error
Attempting to run Scrapydweb with the latest SQLAchemy (1.4 as of now) which is added when running pip install scrapydweb, throws errors. Rolling back to 1.3.2 fixed it for me.
What database backend are you using? if postgresql, sqlalchemy removed in 1.4 support for URLs of the form postgres:// for postgresql://. see this.
This was just based on the default db that comes with scrapydweb, I noticed I got errors thrown when pulling from github and following the instructions (whereas it previously never was a problem). Might be fixed now, no clue :)
Can confirm this. Rolling back to 1.3.2 worked for me as well 👍
Fixed in scrapydweb v1.4.1
