bundle platform

bundle-platform - Displays platform compatibility information

bundle platform [--ruby]


platform displays information from your Gemfile, Gemfile.lock, and Ruby VM about your platform.

For instance, using this Gemfile(5):

source ""

ruby "3.1.2"

gem "rack"

If you run bundle platform on Ruby 3.1.2, it displays the following output:

Your platform is: x86_64-linux

Your app has gems that work on these platforms:
* arm64-darwin-21
* ruby
* x64-mingw-ucrt
* x86_64-linux

Your Gemfile specifies a Ruby version requirement:
* ruby 3.1.2

Your current platform satisfies the Ruby version requirement.

platform lists all the platforms in your Gemfile.lock as well as the ruby directive if applicable from your Gemfile(5). It also lets you know if the ruby directive requirement has been met. If ruby directive doesn't match the running Ruby VM, it tells you what part does not.


It will display the ruby directive information, so you don't have to parse it from the Gemfile(5).
