Unable to start sidekiq, load_missing_constant

Development

AI 生成的摘要

Jen_Lijo is experiencing an issue with starting bundle exec sidekiq due to a load_missing_constant error related to the Version constant. They have tried uninstalling a plugin and checked their local Ruby and app, but the issue persists.

The error logs show that the issue is with autoloading the Version constant, which is expected to be defined in lib/version.rb.

tgxworld suggests that the issue may be fixed in the latest version, recommending Jen_Lijo to pull down the latest version.

I am trying to start bundle exec sidekiq and it’s failing. I need help debugging this.

The app is up to date and I haven’t seen anyone mentioning this issue. I haven’t updated the gems. I’ve uninstalled the Plugin I was developing in case it was provoking it to crash (it was drawing a route) but I keep getting the same error.

Does this have something to do with my local Ruby (as it’s complaining from my .rvm folder about Unable to autoload constant Version) or is it related to my local app (it says it’s expecting Discourse to define Version)?

Logs look like this:
