When deploying my Rails app I get the following error:
rake aborted!

The file in question is valid, it works on localhost. I also tried running rake assests:precompile
on localhost, it all passes. Finally, I tried to remove the content from the file, git push and redeploy - still got the same error. Only completely removing the file and re-deploying helps.
Would appreciate any ideas.
Here I found help for the same problem you had.
Run rails console and:
JS_PATH = "app/assets/javascripts/**/*.js";
Dir[JS_PATH].each do |file_name|
puts "\n#{file_name}"
puts Uglifier.compile(File.read(file_name), harmony: true)
end
It will show you the file and the line where the Uglifier is making the problem.
