am getting this error while installing
am attached link of error log file

shows that you don't (yet) have the necessary tools installed - as the i2c node requires a compiler to build the necessary binary bindings.
Usually something like sudo apt install build-essential python-dev should be enough to get the pieces required - then retry the install.
Can I ask why you have NR installed under root?
What platform/os are you using?
i will try.. and let you know
when am installed node-red, automatically its created under root folder. Installation problems only with i2c and gpio nodes. Other nodes are working fine. My i2c device is working fine from i2cdetect -y 1. Am using raspberrypi 3. I built OS through buildroot.
Thank you
Good Evening. I tried with python script in node-red. Am getting output.....
