Heroku：预编译资产失败

Question

I am trying to deploy my Ruby on Rails application to heroku but heroku fails during assets precompiling. I precompiled assets locally and everything is working fine. I used following command to precompile assets locally RAILS_ENV=production bundle exec rake assets:precompile . I am getting following errors in Heroku

Answer 1

Just had the same issue, it looks like this has been handled before already. My steps to resolve:

yarn upgrade @rails/webpacker --latest

I had upgrade my version of node to 14.15.0--this may be different to you--using:

nvm install 14.15.0 prior to getting the yarn update to work.

That was it.
