Sprockets DependencyError

[adamyonk]

I get the following error when I try to @import peek in my application.css.sass. Rails 4.1.

Sprockets::Rails::Helper::DependencyError at /
Asset depends on 'peek/bar/production.gif' to generate properly but has not declared the dependency
Please add: //= depend_on_asset "peek/bar/production.gif" to '/app/assets/stylesheets/application.css.sass'

Also, I'm using jQuery 2.1.0 and rails_behaviors (instead of jquery_ujs).

I also tried putting the peek stylesheets in their own manifest and used Sprockets //=require, but it seems like the main peek stylesheet is missing.

The gem is setting my config.assets.paths correctly, though:

Looks like it's correctly in your load path:

"/Users/adamyonk/.gem/ruby/2.1.1/gems/peek-0.1.8/app/assets/stylesheets"

I tried this out locally and it worked on my machine. Is there any way you can create a reproducible example? rails/sprockets-rails#126 may have fixed it.

This is so strange. No errors on rake assets:precompile. I'm also using the peek-performance_bar and it compiles fine:
But peek.css just compiles to a blank file.

Interestingly, if I @import peek or //=require peek, there are no errors, but if I try to @import peek.scss or //=require peek.scss I get the error about needing to add //= depend_on_asset "peek/bar/production.gif".

[adamyonk]

If I go into the gem and rename peek.scss to peek-main.scss and @include peek-main, then it works. It seems like Sprockets is getting confused with having both /stylesheets/peek.scss and /stylesheets/peek/ ?

Gosh, now it's only happening sometimes. I'll keep debugging and re-open this if I think it has to do with peek. Sorry, for the trouble.

No worries! Please do re-open if it happens again.
