I am trying to precompile assets using the command rake assets:precompile RAILS_ENV=production
, but I always get the error below.

Tasks: TOP => assets:precompile
Does anybody has any idea what could be wrong? Thanks.
I found out that my back-up project worked well if I precompile without
bundle update
. Maybe something went wrong with gem updated but I don't know which gem has an error.To explain the problem, your error is as follows:
This means somewhere in
application.js
, your app is referencinguglifier
(probably in themanifest
area at the top of the file). To fix the issue, you either need to remove the reference touglifier
, or make sure theuglifier
file is present in your app, hence the answers you've been providedFix
If you've had no luck with adding the gem to your GemFile, a quick fix would be to remove any reference to
uglifier
in yourapplication.js
manifest. This, of course, will be temporary, but will at least allow you to precompile your assetsReplace
with
rake assets:precompile
(RAILS_ENV=production bundle exec rake assets:precompile
is the exact rake task)Since precompilation is done in production mode only, no need to explicitly specify the environment.
Update:
Try adding the below line to your Gemfile:
Then run
bundle install
.Hope it will work :)
I had this problem today. I fixed it being being explict about my require
I had mine still in the assets group.
Have you added this gem to your gemfile?
move that gem out of assets group and then run bundle again, I hope that would help!
