Anybody has solution ?
Thanks.

What versions of frappe and erpnext are you into?

Seems issue with node.

Please check whether nodejs is located

which node or which nodejs

@ johnskywalker,
how we can check the version of frappe and erpnext?

Welcome to ERPNext

If you have console access:

frappe@ubuntu:~/frappe-bench$ bench version
erpnext 10.1.20
frappe 10.1.21

And two other ways

when i give bench version
i got the following only.

/ErpNext/frappe-bench$ bench version
frappe 10.1.30

is frappe and erpnext is different. if so, i installed frappe can anyone suggest how to install erpnext

Yes you seem to be missing erpnext, that requires frappe. You best follow the official install steps GitHub - frappe/bench: CLI to manage Multi-tenant deployments for Frappe apps

What I did was use the production method on linux 16.04. However apt install python-dev build-essential python-setuptools instead of the ones that are in the github setup. I found it to be (mostly) smooth sailing from there.
