I am following along in a rails course and am getting this below error telling me to install the tzinfo-data gem. However, the gem is installed. It’s in my gemfile. I can find the folder in my Ruby directory. Why is this still telling me to install tzinfo-data?

command line response and gemfile below:

C:UsersKevinLambDocumentssitesdemo_project>rails db:schema:dump
rails aborted!
TZInfo::DataSourceNotFound: tzinfo-data is not present. Please add gem 'tzinfo-data' to your Gemfile and run bundle install
C:/Users/KevinLamb/Documents/sites/demo_project/config/environment.rb:5:in `<main>'

Caused by:
TZInfo::DataSources::ZoneinfoDirectoryNotFound: None of the paths included in TZInfo::DataSources::ZoneinfoDataSource.search_path are valid zoneinfo directories.

Gemfile in the demo_project directory I am working in:

    Linking to this post for the answer. I tried a lot of different solutions but this is the only one that worked: tzinfo-data issue when starting new rails project


  2. There’s a bug in Bundler that means there’s no valid platform value that will match 64-bit Ruby 3.1 on Windows.

    With gem "tzinfo-data", platforms: %i[ mingw mswin x64_mingw jruby ] in your Gemfile (or any platforms option), Bundler will exclude tzinfo-data from the bundle and you’ll get the TZInfo::DataSourceNotFound error.

    The solution is to remove the platforms option from the tzinfo-data line in the Gemfile and then run bundle install:

    gem 'tzinfo-data'
