It's failing because in --dry-run, we don't actually run any commands, so we can't guess the passenger version. There's really no reasonable way to work around this, other than to log a fatal error and exit. I'm going to make this a more graceful process.

Thanks for your answer.
As i understand it, a dry run shouldn't change any state on the deployment's destination servers.
But how is running a command like passenger -v or any other version checking a bad thing?
I think in this form, the capistrano/passenger plugin in dry-run mode is unusable, even with a fatal error.

a dry run shouldn't change any state on the deployment's destination servers.

That may be one possible reasonable definition of dry run, but unfortunately, that's not how it's currently implemented in capistrano 3. A dry-run simply prints out all the commands it would run.

capistrano-passenger runs a command, and uses the result to decide what command to do next. If we just print out the command, but don't actually run it on the host, then we can't print out the next command, because we don't know what the next command will be.

We can stub a result (which other capistrano add-ons appear to do accidentally), but that would be misleading, if the intention is to give you a realistic idea of what commands will be run in real life.

Anyway, pull the latest from github and you'll see how I work around this. I'm planning on releasing an updated gem soon but waiting for feedback on a few issues first.

Got same error today, after debugging, found out it's because the remote command "passenger -v" is getting some error messages from rvm before the actually version showed up. In my case, they are something like

[32mRVM used your Gemfile for selecting Ruby, it is all fine - Heroku does that too,
DEBUG [791c8229] you can ignore these warnings with 'rvm rvmrc warning ignore > /home/park/park_deploy/current/Gemfile'.
DEBUG [791c8229] To ignore the warning for all files run 'rvm rvmrc warning ignore allGemfiles'.
DEBUG [791c8229] [0m
DEBUG [791c8229] Phusion Passenger version 5.0.10

Because of these, the regular expression used to get version number returned nill, so the exception was throwed. Get rid of the warning message by running passenger -v command fixed the issue. Maybe a throught match for multiline is better in this case.

Grab passenger ver even it's not first line

For capistrano#20 , if the version info returned by `passenger -v` is not the first line, the original regular expression will return nil so that error will be raised. This might happen sometime, such as RVM might give a warning when running a command.

I also start to have this problem (not using dry run) after updating to passenger 5.0.10.

But i seem unable to use bleeding edge
gem 'capistrano-passenger', git: 'https://github.com/capistrano/passenger.git', branch: 'master'
It just doesn't work. Just refutes to be required.

Right, i had to build the gem.

$ cd `bundle show capistrano-passenger`
$ gem build capistrano-passenger.gemspec
$ gem install capistrano-passenger-0.1.0.gem
