=20.5.0"}

I am building a next JS application when I tried to run that I am getting an error saying node version not supported. so I tried to update my node version I tried lot commands specified in various resource. I tried to delete the path provided in the environment variables but there is no path named node JS in my environment variables. And also I tried to delete npm cache node-gyp and folders in my system but also I am getting errors. What is the issue here? Here are the errors I get:
