Hi,
I just got set up with a new Jekyll theme (Forma) and the theme designer has advised I move from gitPage to Netlify, which I did.
I successfully deployed my new site a few times, but then got an error I can’t fix :

9:46:21 PM: [DEPRECATED] The --path flag is deprecated because it relies on being remembered across bundler invocations, which bundler will no longer do in future versions. Instead please use bundle config set path '/opt/build/cache/bundle', and stop using this flag
9:46:21 PM: [DEPRECATED] The --binstubs option will be removed in favor of bundle binstubs

9:46:22 PM: 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.
