bootstrap-rails | Twitter Bootstrap CSS | Theme library

Their docs make it look like you only need to set the URL for redis and not an instance of redis https://github.com/resque/resque/blob/master/README.markdown#configuration

The root of the problem seems to be bundler. What operating system and Ruby version are you using? It may be a problem with old OpenSSL library, so you can not install bundler and everything after it.

If you are using jRuby (your gem list output tells so), your problem seems to be the same as described in link. And there is a solution as well.

Maybe you forgot to set 2.1.2 version of ruby as global? (rbenv set global 2.1.2)

I fixed this by changing the heroku buildpack to heroku/ruby (bundler was giving me issues)

If you are using rails 5, try this:

The latter uses sass while the former uses less, since rails typically uses scss (sass) I would go with https://github.com/twbs/bootstrap-rubygem but do keep in mind that uses bootstrap 4. If you need 3 or less, use https://github.com/twbs/bootstrap-sass

This doesn't seem to be a Devise issue. It looks like the image apple-touch-icon-144x144-precomposed.png doesn't actually exist in your project. Rails is throwing you an error because it can't find it.

The apple-touch-icon-144x144-precomposed.png that rails cannot find is from the bootstrap theme. Those images should be in the folder of the theme that you downloaded (unless you somehow deleted the originals...then you would have to download it again). If you don't need those images anyway, you can just delete all of the favicon link tags from the of your html layout and the error will go away.

-or-

You can use a favicon generator to create the ones you want and save them with those specific file names (in your case: apple-touch-icon-144x144-precomposed.png) into your project and the errors will go away as well. But once again, if you don't need them then there's no point in doing that.

Honestly, I'm not sure why you are encountering this issue if you didn't alter the original files from the theme, but you should read THIS & THIS to see if it helps clarify things.

Hope that helps & good luck with your project!

Without any claim of completeness, here are a few different reasons why you might want to include Bootstrap via a gem.

First, it allows you to customize the library in a much more powerful way than including it through a reference. If you browse through the linked project's README, you'll notice that you can use LESS or SASS, and overwrite individual variables within Bootstrap. This makes it much easier to create your own Bootstrap theme for example, and create clean and maintainable CSS classes.

Second, gems often provide much more functionality than just including Bootstrap. They make it easy to scaffold new pages by providing generators or overwriting templates in Rails. And they sometimes even come with custom Javascript implementations for certain Bootstrap features to make it easier to integrate them with Rails. For an example, just look at the linked library again and its helper methods for navbars:

• Cloned twitter-bootstrap-rails repo
• Analyzed latest commits
• Changed gemspecs
• ????
• PROFIT!!!

Assuming you have used the code from the how-to link - just try adding a few puts logs to console and see what you're getting:
