How start erpnext app (just frappe show) in beta3

hi, i install frappe and erpnext based on tutorial centos 8, my question is when install version-12 of erpnext the site apear erpnext 12.x but if install erpnext 13-beta the install just show frappe 13 but not erpnext 13 (bot on beta of course). Unknow why if just change version the erpnext not install or work but frappe 13 beta work fine.

of course i install frape first and after erpnext.

resolved. Just need install 3 times the “bench install-app erpnext” and work, unknow if when download lost any but in thirt time work.

regards.
