load_rake_tasks!': Could not detect rake tasks (LanguagePack::Helpers::RakeRunner::CannotLoadRakefile

Error)

I can run

bundle exec rake -P

just fine on my local environment, also while setting RAILS_ENV=production. Thx!

rexml

is not part of Ruby’s stdlib anymore from v3.0. Either you’re running ruby < 3 locally, or you have

rexml

installed system-wide. Either way, the solution is adding

rexml

to the Gemfile.

@waiting_for_dev thanks so much🫡, adding

rexml

to the

Gemfile

fixed the issue.

happy to help!
