John -

If you’re using rvm, I’d suggest not using the ‘jruby’ and ‘jruby -S’
forms, and just using the plain ‘ruby’, ‘rspec’, etc. notations.

I don’t know that this is the cause of the problem, and what you did
looks to me like it should work, but it’s possible.

To simplify the use of Nailgun, I have a set of scripts that can easily
be created in one command, in my blog article about Nailgun at
http://www.bbs-software.com/blog/2012/09/15/hello-nailgun-goodbye-jvm-startup-delays/.

Also, I’m not sure, but I’m wondering if your path might be mangled.
Here’s a command that will list each directory in the path on its own
line:

echo $PATH | tr : \n

You’re very welcome

I don’t know about the Psych/Yecht issue. It’s confusingmy understand
is that both are separate YAML parsers, so it sounds like some kind of
configuration mixup.

I did find these message threads that might provide clues for you:

Best of luck,

Running ‘ruby’ solved my issue. Thanks for the help! Much appreciated.

I love your blog post and aliases - very handy. :slight_smile:

The only barrier to getting everything working now is my

‘uninitialized constant Psych::Yecht’

error - NameError: uninitialized constant Psych::Yecht with jruby 1.7.1 - JRuby - Ruby-Forum

Do you have any ideas on how to solve that?
