Serial port error while installing modbus tcp

[nilesh441]

I have successfully installed node-red on Cyclone 5 SOC and accessed its GPIO from custom nodes. Now I am trying to install modbus tcp node on this board but I am getting Serial port error. I got the same error on Toradex VF61 module too. I don't know why it is giving serial port error for modbus tcp? Error is as follows:

root@cyclone5:~# npm install node-red-contrib-modbustcp

EACCES: permission denied, mkdir '/home/root/node_modules/serialport/build

This looks like a permission issue. This node is based on the jsmodbus node package. Contact those developers for further troubleshooting.
