Cannot determine timezone from nil (ArgumentError)

I want to use Smashing (a sinitra-based dashboard-making tool) on a Windows machine. When lanching the the default project using smashing start I get the following error :

Try setting `ENV['TZ'] = 'Continent/City'` in your script (see https://en.wikipedia.org/wiki/List_of_tz_database_time_zones)

After looking online, I found out that this issue is probably due to Windows, and I tried adding gem 'tzinfo-data' in my Gemfile, but that didn't change anything. Do you know how I could fix that ?

Solution

  • ENV['TZ'] = 'Europe/Paris' at the very beginning of config.ru (before the require) worked
