My Gemfile looks like this:

source 'https://rubygems.org'

gem 'rails', '~> 5.0.0'
gem 'pg'
gem 'puma', '~> 3.0'
gem 'httparty', '~> 0.14.0'

gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.2'
gem 'jquery-rails', '~> 4.1', '>= 4.1.1'
gem 'haml-rails', '~> 0.9.0'
gem 'bootstrap-sass', '~> 3.3', '>= 3.3.7'
gem 'owlcarousel-rails', '~> 1.1', '>= 1.1.3.3'
gem 'font-awesome-rails', '~> 4.6', '>= 4.6.3.1'


gem 'turbolinks', '~> 5'
gem 'jbuilder', '~> 2.5'
# Use Redis adapter to run Action Cable in production
# gem 'redis', '~> 3.0'

gem 'therubyracer'
gem 'execjs'

group :development, :test do
gem 'byebug', platform: :mri
end

group :development do
gem 'web-console'
gem 'listen', '~> 3.0.5'
gem 'spring'
gem 'spring-watcher-listen', '~> 2.0.0'
end

gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]


I tried both with and without:

gem 'therubyracer'
gem 'execjs'


Nothing helps. Running rake assets:precompile locally on my mac works...

Answer

It may have something to do with javascript/coffescript syntax. Check if you have let, it shout be replaced with var.
