¿Dónde se instalan las gemas en paquete?

Where does bundle install gems to?

The location to install the gems in the bundle to. This defaults to Rubygems’ gem home, which is also the default location where gem install installs gems. This means that, by default, gems installed without a –path setting will show up in gem list .

When we run bundle install in a project , if there is no Gemfile. lock exist, Bundler will fetch all remote sources, resolve dependencies and install all needed gems. When we update a version of a gem then run bundle install , only the gem will be updated.

When you run bundle install , Bundler will persist the full names and versions of all gems that you used (including dependencies of the gems specified in the Gemfile(5)) into a file called Gemfile.

Setting up Bundler

1. Open a terminal window and run the following command:
2. Navigate to your project root directory.
3. Install all of the required gems from your specified sources:
4. Inside your app, load up the bundled environment:
5. Run an executable that comes with a gem in your bundle:

bundle package will copy all the gems required by your application into the vendor/cache folder. This also includes dependencies required by the gems.

The bundle exec command ensures that executable programs installed by Gems don’t interfere with your app’s requirements. For instance, if your app needs a specific version of rake but the default version of rake differs, bundle exec ensures that you can still run the specific rake version compatible with your app.

Typical examples of bundling include option packages on new automobiles and value meals at restaurants. In a bundle pricing scheme, companies sell the bundle for a lower price than would be charged for items individually.

A bundle is a package of things wrapped together. To wrap things together in a compact way is to bundle them. A baby wrapped up in a blanket is a bundle of joy, and if it’s cold outside, bundle up! Bundle comes from the Middle Dutch word for bind, which is what you do when you bundle stuff — you bind it together.

Bundler provides a consistent environment for Ruby projects by tracking and installing the exact gems and versions that you need. Bundler prevents dependencies and ensures that the gems you need are present in development, staging, and production.

What’s the difference? A Gemfile.lock is auto-generated & it says exactly what versions of every gem were installed. Bundler will install these versions so when you deploy this application to production, or share your project with other developers, everyone will be working with an identical set of gems.

This is what you should see when running the bundle install command: Bundle complete! 18 Gemfile dependencies, 78 gems now installed. Use `bundle info [gemname]` to see where a bundled gem is installed.

The executables installed into bin are scoped to the bundle, and will always work. Bundler is also an easy way to create new gems. Just like you might create a standard Rails project using rails new, you can create a standard gem project with bundle gem.
