Hello After updating node red ı can not install again node red Modbus Serial Rs 485 again
I moved your question into general as “Core development” is, as per the description, the place for questions if you are helping to code the node-red application.
Please post the log file you get when you start Node-RED.
What machine you are running Node-RED on as well as any errors when you try to install the node.
Node Red is running on raspberry pi It is giving 'Failed to install:node-red-contrib-serial-modbus
Check the log for more information
I would suggest you check the log then.
As well as supplying the other information I asked for…
Which node is it that you are trying to install? (node-red-something).
Colin, I think this gives you the information you asked for
cd ~/.node-red npm install node-red-contrib-serial-modbus
and copy/paste the result here.

you still haven’t posted the startup log for node-red which contains the details of what version of node-red what version of nodejs and what operating system you are running on.
It was also be useful to know what platform you are running this on
Once Node-RED has started, point a browser at http://192.168.168.77:1880
On Pi Node-RED works better with the Firefox or Chrome browser
Use node-red-stop to stop Node-RED
Use node-red-start to start Node-RED again
Use node-red-log to view the recent log output
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot
Use sudo systemctl disable nodered.service to disable autostart on boot
To find more nodes and example flows - go to http://flows.nodered.org
Starting as a systemd service.
Started Node-RED graphical event wiring tool.

Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.
