Bundle complete! 14 Gemfile dependencies, 59 gems now installed.
Gems in the group production were not installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.
Post-install message from rdoc:
Depending on your version of ruby, you may need to install ruby rdoc/ri data:

<= 1.8.6 : unsupported
 = 1.8.7 : gem install rdoc-data; rdoc-data --install
 = 1.9.1 : gem install rdoc-data; rdoc-data --install
>= 1.9.2 : nothing to do! Yay!

All good till here.

Then i added the code @import "bootstrap"; into my styles.css.scss file. I restarted the server for the changes to reflect in localhost:3000 Then this happens:

    rails server
Warning: Running `gem pristine --all` to regenerate your installed gemspecs (and deleting then reinstalling your bundle if you use bundle --path) will improve the startup performance of Spring.
Could not find autoprefixer-rails-5.1.7 in any of the sources
Run `bundle install` to install missing gems.

I tried running 'bundle install' but to my dismay the same error crept up again and again. So in a jist, the server doesn't start citing "it couldn't find autoprefixer-rails-5.1.7 gem " but if you check the script above it has actually installed it.

Please help me fix this.

Answer 1

I ran the command bundle exec rails s . The server runs now. But it still isn't running if the command rails s is executed. It throws the same error.
