description <<~DESC
Use the **gem_package** resource to manage gem packages that are only included in recipes.
When a gem is installed from a local file, it must be added to the node using the **remote_file** or **cookbook_file** resources.
Note: The **gem_package** resource must be specified as `gem_package` and cannot be shortened to `package` in a recipe.
Warning: The **chef_gem** and **gem_package** resources are both used to install Ruby gems. For any machine on which #{Chef::Dist::PRODUCT} is
installed, there are two instances of Ruby. One is the standard, system-wide instance of Ruby and the other is a dedicated instance that is
available only to #{Chef::Dist::PRODUCT}.
Use the **chef_gem** resource to install gems into the instance of Ruby that is dedicated to #{Chef::Dist::PRODUCT}.
Use the **gem_package** resource to install all other gems (i.e. install gems system-wide).
DESC
examples <<~EXAMPLES
The following examples demonstrate various approaches for using the **gem_package** resource in recipes:
**Install a gem file from the local file system**
```ruby
gem_package 'right_aws' do
source '/tmp/right_aws-1.11.0.gem'
action :install
end
```
**Use the `ignore_failure` common attribute**
```ruby
gem_package 'syntax' do
action :install
ignore_failure true
end
```
