derailed bundle:mem can't load warden on MRI2.3.3?

[hakusaro]

Hiya. I'm really stumbling through this trying to get anything derailed does to work. I'm trying to debug a Sinatra application, and aside from not getting DERAILED_APP to work at all, I can't even get bundle exec derailed bundle:mem to work to benchmark gems. I have derailed in my Gemfile, and I've run bundle install but it dies immediately trying to load warden.

bundle exec derailed bundle:mem

bundler: failed to load command: derailed (/Users/shank/.rbenv/versions/2.3.3/bin/derailed)
LoadError: cannot load such file -- warden

What am I doing wrong?

[schneems]

Do you see warden if you run:

$ bundle exec gem list

[hakusaro]

Ugh, nope. It's not on the list.

Reading the trace more, I commented out sinatra_more in the Gemfile on a whim and sure enough, it works fine now. I guess maybe it's a gem conflict? Oh well. Seems to be at least more helpful if I can get something to work by commenting out a gem.

@schneems should I go ahead and make an issue for figuring out how to load a modular Sinatra app, or is there an alternative place to ask questions? I'm really not sure at all how to go about this.

Sorry for burning your time :c

[schneems]

I honestly don't know. I've really only ever used this with Rails apps. I added the arbitrary rack extension to allow for custom use cases. If you get something working feel free to write up some docs.
