This is for you if Passenger gives you the following useless error message.

Passenger encountered the following error:\
The application spawner server exited unexpectedly: Unexpected end-of-file detected.

Exception class:

PhusionPassenger::Rack::ApplicationSpawner::Error

Most often this happens because you are missing a gem. Usually Passenger would tell you about that but in some cases it can't.

To resolve this issue, run:

bundle install

If this does not do the trick for you, take a look at the Apache log files for de...

If you'd like to preview the crontab that whenever will deploy, run the following:

bundle exec whenever

This will print the cron syntax without modifying your local crontab.

This error can be caused by the mysql2 gem under mysterious circumstances. You need to remove it with gem uninstall mysql2 and then reinstall it (or just run bundle).

gem pristine mysql2 will not be enough.

New Features

• Deployment ready for Opscomplete
• Copying view and controller templates over to target application during
  basics configuration or via new command katapult templates.
• "Usage" section in README rewritten: Now describes two usage scenarios.

Improvements

• Generating a fixed Gemfile.lock. Run bundle update after code generation to
  update all gems to recent versions.
• Better deployment with Webpack
• Navigation only rendered if requested
• Some minor fixes

When there's a Gemfile.lock in your working directory that you cannot remove by either checkout, reset [--hard], stash, probably Rails' Spring is the culprit and not Bundler itself.

Fix

spring stop

The author of the linked Stackoverflow post supposes Spring re-writes the Gemfile.lock on change to ensure all Spring processes are using the same gem versions. Meh.

Traveling Ruby is a project which supplies self-contained, "portable" Ruby binaries: Ruby binaries that can run on any Linux distribution and any OS X machine. This allows Ruby app developers to bundle these binaries with their Ruby app, so that they can distribute a single package to end users, without needing end users to first install Ruby or gems.

Angular-xeditable is a bundle of AngularJS directives that allows you to create editable elements.

Such technique is also known as click-to-edit or edit-in-place.

It is based on ideas of x-editable but was written from scratch to use power of angular and support complex forms / editable grids.
