"rake assets:precompile" gives punc error

Question

I'm trying to precompile my assets for production, but rails doesn't seem to be cooperating.

$ bundle exec rake assets:precompile /home/drderp/.rvm/rubies/ruby-1.9.3-p194/bin/ruby /home/drderp/.rvm/gems/ruby-1.9.3-p194@global/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets rake aborted! Unexpected token punc, expected punc (line: 213, col: 13, pos: 5986)  Error     at new JS_Parse_Error (<eval>:1720:22)     at js_error (<eval>:1728:15)     at croak (<eval>:2189:17)     at token_error (<eval>:2196:17)     at expect_token (<eval>:2209:17)     at Object.expect (<eval>:2212:40)     at Object.1 (<eval>:2763:38)     at prog1 (<eval>:2770:28)     at <eval>:2560:51     at maybe_unary (<eval>:2665:27)   (in /home/drderp/projects/p/app/assets/javascripts/application.js)  Tasks: TOP => assets:precompile:primary (See full trace by running task with --trace) rake aborted! Command failed with status (1): [/home/drderp/.rvm/rubies/ruby-1.9.3-p194/b...]  Tasks: TOP => assets:precompile (See full trace by running task with --trace) 

This is the entire contents of application.js:

// This is a manifest file that'll be compiled into application.js, which will include all the files // listed below. // // Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts, // or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path. // // It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the // the compiled file. // // Since javascript, no matter what order you load it in, executes in different order, it doesn't // matter // // WARNING: THE FIRST BLANK LINE MARKS THE END OF WHAT'S TO BE PROCESSED, ANY BLANK LINE SHOULD // GO AFTER THE REQUIRES BELOW. // //= require jquery 

Rails version 3.2.8, running on Ruby 1.9.3.

Here's bundle exec rake assets:precompile --trace, as requested:

Answer 1

A more universal way to find the problem in js-assets: 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)) end 

Answer 2

I had this same problem. Open your Javascript console in the browser and see where there is an error. I suspect (because it was the solution to my problem), that one of your JS files has an error and it is most likely whatever JS you wrote that used a ">" symbol.

Good luck error hunting.
