Hi,
I have followed the tutorial on creating a new app, i called mine Learning_Management but kept pretty much everything else the same from the tutorial (it is called Library_Management).
After creating the app we have to install the app on our site, now the site works fine, i have already created some custom fields and DocTypes in the HR Module. Hoping some one can help here please 
So I ran the command and get the following:
frappeuser@linux5:~/frappe-bench/apps$ bench --site site1.local install-app Learning_Management
Installing Learning_Management…
