Sidekiq: Uninitialized constant Sidekiq::CronParser

[spinx]

Ruby 2.4.0
Using sidekiq 5.0.0
Using sidekiq-pro 3.5.0
Using sidekiq-ent 1.5.3

When upgrading to 5.0 and opening web ui at CRON tab, it blows up with this error. Can't figure out why it is not loading properly. Tried the usual re-install and such.

Rack file:

require 'sidekiq-ent'
require 'sidekiq-ent/web'

Sidekiq.configure_client do |config|
config.redis = { url: ENV['SIDEKIQ_REDIS_URL'] }
end

run Sidekiq::Web

Fixed in 1.5.4 (which likely won't be out for a while). Add require 'sidekiq-ent/periodic/cron' to your initializer to fix.

1.5.4 is out with this fix since I've had multiple complaints. :-)
