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 "https://rubygems.org"
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.
