I got error when i start rails project as the following error. I feel it may be because of incompatible gem version but i am not sure if it is because of Bundler gem or Valium gem. Thank in advance for the reply.

You need to install NodeJS, please check out https://nodejs.org/en/download/
But if you want to keep developing with Rails on Windows, you should check the WSL https://msdn.microsoft.com/pt-br/commandline/wsl/install_guide

Try bundle update instead of bundle install . and also do you have node.js installed?
I updated Ruby to 2.2.2 from 2.0.0 because I think it may have been causing issues with Heroku, but now when I try and start the rails server I'm getting a name error, and because I'm new to RoR I have no idea what's causing it.
Here is my log:
