    text
    copied!<p>I go to redeploy my heroku apps with a new gem in Gemfile and it crashes on startup </p> <pre><code>/app/vendor/bundle/ruby/1.9.1/gems/activesupport-3.2.3/lib/active_support/dependencies.rb:251:in `require': libruby.so.1.9: cannot open shared object file: No such file or directory - /app/vendor/bundle/ruby/1.9.1/gems/bcrypt-ruby-3.0.1/lib/bcrypt_ext.so (LoadError) </code></pre> <p>This is happening no matter what branch I deploy (old stable ones...) and only fixes by doing a <code>heroku rollback</code>.</p> <p>I believe this is caused by heroku recently updating their ruby 1.9.3 because I was having this issue <a href="https://stackoverflow.com/questions/12880632/heroku-app-crashes-with-libruby-so-1-9-cannot-open-shared-object-file">Heroku app crashes with &#39;libruby.so.1.9: cannot open shared object file&#39;</a> . Removing the nokogiri gem stopped the exception I was getting but then there's still this. More similar errors occur when I add new gems. </p> <p>The whole problem was solved by deploying to a new heroku app but that's not something I can just do on my production server. </p> <p>Any ideas on fixing the issue or somehow "refreshing" my app?</p> <p>my gemfile:</p> <pre><code>source "https://rubygems.org" ruby "1.9.3" gem "rails", "3.2.3" gem "thin" # Bundle edge Rails instead: # gem "rails", :git =&gt; "git://github.com/rails/rails.git" gem "mongoid" gem "devise" gem "haml" gem "sass" gem "exceptional" gem "kaminari" gem "mongoid_search" #gem "nokogiri" gem "bson_ext" gem "heroku-mongo-backup" gem "aws-s3" # Gems used only for assets and not required # in production environments by default. group :assets do gem "haml-rails", "~&gt; 0.3.4" gem "sass-rails", "~&gt; 3.2.3" gem "coffee-rails", "~&gt; 3.2.1" # See https://github.com/sstephenson/execjs#readme for more supported runtimes # gem "therubyracer", :platform =&gt; :ruby gem "uglifier", "&gt;= 1.0.3" end gem "jquery-rails" group :test do gem "mongoid-rspec" end # To use ActiveModel has_secure_password # gem "bcrypt-ruby", "~&gt; 3.0.0" # To use Jbuilder templates for JSON # gem "jbuilder" # Use unicorn as the app server # gem "unicorn" # Deploy with Capistrano # gem "capistrano" # To use debugger # gem "ruby-debug19", :require =&gt; "ruby-debug" # group :development do gem "letter_opener" end </code></pre>
