How to fix rake assets:precompile errors?

Question

Ruby on Rails

I'm trying to make a team

RAILS_ENV=production bundle exec rake assets:precompile

While doing this I get an error:

ExecJS::ProgramError: Unexpected token: operator (>) (line: 48027, col: 50, pos: 1986183)

/home/parts-soft/.rvm/gems/[email protected]/gems/execjs-2.6.0/lib/execjs/ruby_racer_runtime.rb:75:in `block in lock'

When I do

RAILS_ENV=production bundle exec rake assets:precompile:all

Sprockets::FileNotFound: couldn't find file 'handlebars.runtime'
  (in /home/oil/www/oil/releases/20171122232617/apps/www/app/assets/javascripts/application.js:32)

The error is displayed in more detail.
What can be done in this situation? What is the problem I can't understand?
In general, these files were not touched.

I treated similar strange problems by installing nodejs on the development environment (now you have therubyracer as a js engine)
