# Show The Bundler Location Of An Installed Gem
|
|
|
|
When you run `bundle install` with a project, it is going to install all the
|
|
gems specified by your project in a vendored location relative to the location
|
|
of your Ruby version install.
|
|
|
|
If you want to find the location of a specific gem, you can ask bundler with
|
|
`bundle show <gem-name>`.
|
|
|
|
Here I ask where the `rspec` gem is.
|
|
|
|
```bash
|
|
$ bundle show rspec
|
|
/Users/jbranchaud/.asdf/installs/ruby/3.1.3/lib/ruby/gems/3.1.0/gems/rspec-3.12.0
|
|
```
|
|
|
|
I could `cd` into that directory to have a look around at the source. That's a
|
|
great way to learn more about how our dependencies work.
|
|
|
|
I could even inject some debugging statements (e.g. `binding.irb`) which the
|
|
program using these gems will break on. Not often, but sometimes you need to
|
|
dig in this deep to understand what is causing a tricky bug or why code isn't
|
|
behaving like you'd hoped. Just remember to remove those statements when you're
|
|
done.
