rake assets:precompile for my rails project throws below error:

rake aborted! Current ExecJS runtime does't support ES6. Please install latest Node.js.

Below is the environment information:

rails -v
Rails 5.0.7

ruby -v
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux]

node -v
v6.11.1

I tried reinstalling all my gems. But still, the error comes. OS is RHEL.

gem 'autoprefixer-rails', '8.6.5'

in my Gemfile
