ruby on rails “usr/bin/env: ‘ruby2.3’: No such file or directory”

问题

I got some problem when i typing bundle exec rake db:migrate on terminal then i received the result like `/usr/bin/env: ‘ruby2.3’: No such file or directory

回答1:

I had the same problem but when running:

rails new my_application

but after reinstalling the rails gems by:

gem install rails

it worked just fine and I could run:

rails new my_application
bundle install

and

bundle exec rails s

without any problems.

For me, the problem was with a cached set of gems (on CircleCI 2.0). I changed my base image which changed the ruby location. If you tried to bundle install with one ruby, removed it then switched to another, then this appears to cause the problem.
