Rails db:migrate can't find gems

Question

I'm trying to run the rake db:migrate command, but when I run it it tells me there is not a gem installed. I'll run bundle install and it'll execute correctly, but then It'll once again tell me that a gem is not installed. The gem it's telling me is not installed is the minitest-5.8.0 .

This is what shows up after I do bundle install

Your bundle is complete!
Gems in the group production were not installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.

When I run which ruby It'll show me the path /usr/local/bin/ruby and when I run bundle show minitest it'll show me /Library/Ruby/Gems/2.0.0/gems/minitest-5.8.0

Why is it not detecting that minitest is installed.

Answer 1

Try running rake db:migrate with bundle exec .

Your complete run command should be bundle exec rake db:migrate .

Answer 2

I would try reinstall your ruby

rvm get stable
rvm reinstall ruby-2.3.0
