Hi ,

May we know the operating environment that Bench is being installed in? It looks like the cron package may not be installed.

I am on Ubuntu 20.x
Python 3.9

I noticed that after I posted the issue here and fixed that but now I am getting a different error:

make: Leaving directory '/home/frappe/frappe-bench/apps/frappe/node_modules/node-sass/build'
Build failed with error code: 1

Try bench setup --requirements and bench build

Thanks a lot for your help.
since there are some other breaking bugs for version 13 here in the forums and in github I decided to stay with version 12.
