socketio no working

[pvanthony]

Did a clean install on ubuntu 24 minimal.

The installation went well but it did state that some services did not start correctly.

Erpnext 16 first then tried erpnext 15 but getting the same issue.

Did "supervisorctl status" got the following.

frappe-bench$ supervisorctl status
/usr/lib/python3/dist-packages/supervisor/options.py:13: UserWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html. The pkg_resources package is slated for removal as early as 2025-11-30. Refrain from using this package or pin to Setuptools<81.

frappe-bench-workers:frappe-bench-frappe-short-worker-0   RUNNING   pid 2424, uptime 0:13:10

Did some search in google to fix it but cannot find a solution.

Here is the error from the socket logs

Error: Cannot start socketio: node not found and the python backend is unavailable. Install node or a frappe version with frappe.realtime.server.
Error: Cannot start socketio: node not found and the python backend is unavailable. Install node or a frappe version with frappe.realtime.server.

When I run the following, it seems to be working.

~/frappe-bench$ bench socketio
Realtime service listening on: ws://0.0.0.0:9000

What am I missing?

From searching the internet, it seems that supervisor is trying to run with another node. And since there is no node installed using apt-get, it just fails.

So did the following to link to the node installed by the script.
ln -s /home/frappeuser/.nvm/versions/node/v20.20.2/bin/node /usr/bin/node

Now socketio is running.
Did a bench update as well bench restart.
Also did a machine reboot and it still works.

I hope someone can comment if this is the right thing to do.

Claude helped me with this:

sudo ln -sf /home/frappeuser/.nvm/versions/node/v24.21.0/bin/node /usr/local/bin/node
sudo ln -sf /home/frappeuser/.nvm/versions/node/v24.21.0/bin/npm /usr/local/bin/npm
sudo ln -sf /home/frappeuser/.nvm/versions/node/v24.21.0/bin/npx /usr/local/bin/npx

it's been good so far.

This is a much better solution. Thank you for sharing the solution. It has been helpful.

Could this be included in the install script? Safe to do that?

Improving the solution further:

right in between the lines 604 and 606 in the current install script:

sleep 2

if [[ -z "$py_version" ]] || [[ "$py_major" -lt 3 ]] || [[ "$py_major" -eq 3 && "$py_minor" -lt "$required_python_minor" ]]; then

adding the following:

echo -e "${YELLOW}Linking nvm-installed Node into /usr/local/bin so supervisor can find it...${NC}"
nvm_node_bin_dir="$(dirname "$(nvm which default)")"
sudo ln -sf "$nvm_node_bin_dir/node" /usr/local/bin/node
sudo ln -sf "$nvm_node_bin_dir/npm" /usr/local/bin/npm
sudo ln -sf "$nvm_node_bin_dir/npx" /usr/local/bin/npx
echo -e "${GREEN}Linked $(readlink -f /usr/local/bin/node) -> /usr/local/bin/node${NC}"
sleep 1

Claude did help debug this. I created a fork for testing at https://github.com/idecable/erpnext_quick_install/blob/main/erpnext_install.sh

Thank you for the fork. I will test it out and report back.
