`spring` fails if the gem is bundled using `path:`

[dadooda]

Hey team,

Here's an issue. Current version is 2.0.2, full-repo clone to vendor/gems/spring (see below).

Gemfile:

group :development do
  gem "spring", path: Pathname(__dir__).realpath + "vendor/gems/spring"

$ bundle install
$ bundle exec spring
You've tried to invoke Spring when it's already loaded (i.e. the Spring constant is defined).

This is probably because you generated binstubs with Spring 1.0, and you now have a Spring version > 1.0 on your system. To solve this, upgrade your bundle to the latest Spring version and then run `bundle exec spring binstub --all` to regenerate your binstubs. This is a one-time step necessary to upgrade from 1.0 to 1.1.

Here's the backtrace:

Possibly related: spring 1.7.2, Gemfile uses github method to get some gems... I get the <gem...> is not yet checked out. Run bundle install first. (Bundler::GitError) message unless I leave a terminal window open after running bundle exec spring in the terminal window. Binstubs have been created and updated. I find myself constantly having to use bundle exec rake ... , bundle exec rails c etc. which defeats the point of spring.

It seems the spring daemon is staying attached to the terminal and terminating when the terminal is closed?
