Which rails gem do I need?

Question

I just deployed a rails application to heroku after which my rails server no longer works.It gives the following error

bin/rails:4:in `require': cannot load such file -- rails/commands (LoadError)
from bin/rails:4:in `<main>'

I ran gem query --local and saw that rails 4.1 was installed.Can someone explain to me what this error means and how to resolve it

Answer 1

You need to check which rails is on your PATH... you probably installed are running on a mac that have an native rails.

Read this documentation to learn how to set your default rails instance.
