How can I restore my Rails 4 binstubs?

Question

I regenerated my binstubs at some point. It used to be that Spring worked flawlessly and after the first time I brought up a Rails console, the console would come up instantly.

Now it appears that Spring is no longer running.

When I type:

rails console

I get:

Looks like your app's ./bin/rails is a stub that was generated by Bundler.

In Rails 4, your app's bin/ directory contains executables that are versioned
like any other source code, rather than stubs that are generated on demand.

Here's how to upgrade:

  bundle config --delete bin    # Turn off Bundler's stub generator
  rake rails:update:bin         # Use the new Rails 4 executables
  git add bin                   # Add bin/ to source control

You may need to remove bin/ from your .gitignore as well.

When you install a gem whose executable you want to use in your app,
generate it and add it to source control:

  bundle binstubs some-gem-name
  git add bin/new-executable

Loading development environment (Rails 4.2.3)
[1] pry(main)> 

If I type:

spring rails console

I get the same message, but instead of the console coming up I just get returned to the command line.

How can I get this command working the way it does in a new Rails app?

Answer 1

I didn't want to delete my whole bin directory, and it was already added to git. So I just ran:

rake rails:update:bin

and the messages went away.
