Steps to reproduce rails new test_file

Expected rails to create the files and install the gemfile with no errors.

Actual behavior The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java.

Fetching puma 3.11.0 Installing puma 3.11.0 with native extensions Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

An error occurred while installing puma (3.11.0), and Bundler cannot continue. Make sure that gem install puma -v '3.11.0' succeeds before bundling.

System configuration Ruby version: 2.3.0 Rails version: 5.4.1 Puma version: 3.10.0
