Don't know how to build task 'bundle' - Ruby on Rails

Question

I am trying to precompile my assets:

rake assets:precompile RAILS_ENV=production bundle exec rake assets:precompile

and getting the following error:

Don't know how to build task 'bundle' (See the list of available tasks with "rake --tasks")

After --trace:

** Invoke assets:precompile (first_time)
** Invoke assets:environment (first_time)
** Execute assets:environment
** Invoke environment (first_time)
** Execute environment
** Invoke yarn:install (first_time)

How to fix this problem? I tried to update my gems, re-installed everything, added gem 'rake' and still getting the same error. Thank you very much for your help.

You seem to have mixed up your commands so that you are attempting to call two commands as one.

It appears, you are actually trying to call only this:

RAILS_ENV=production bundle exec rake assets:precompile

With the command you have used originally, you are trying to call the rake tasks named assets:precompile, bundle, exec, rake and again assets:precompile. Since you don't have a rake task named bundle, you got the error you quoted.
