using rbenv on macos does have mjruby binary after install

[mkristian]

after gem install mjruby I get the following

$ gem content mjruby
/Users/cmeier/.rbenv/versions/jruby-9.0.3.0/lib/ruby/gems/shared/gems/mjruby-0.5.2-java/Makefile

and running the right executable directly:

$ /Users/cmeier/.rbenv/versions/jruby-9.0.3.0/lib/ruby/gems/shared/gems/mjruby-0.5.2-java/mruby/build/i386-apple-darwin14/bin/mjruby
RuntimeError: JRUBY_HOME directory is malformed: no lib directory found!

maybe I did something utterly wrong not sure.

What happened when you ran just mjruby?

The mjruby executable needs to be in the JRUBY_HOME/bin dir, so running it from the Gem contents won't work.

Maybe there was a problem because rbenv uses shims, and the Gem tries to install the mjruby executable alongside the shim instead of in the JRUBY_HOME dir?

I was able to get this working like so:

$ rbenv versions
* jruby-9.0.5.0 (set by RBENV_VERSION environment variable)

$ jruby -v
jruby 9.0.5.0 (2.2.3) 2016-01-26 7bee00d OpenJDK 64-Bit Server VM 24.91-b01 on 1.7.0_91-b02 +jit [linux-amd64]

$ jgem install mjruby
Building native extensions.  This could take a while...
Successfully installed mjruby-0.5.2-java
1 gem installed

$ rbenv rehash

$ mjruby -v
jruby 9.0.5.0 (2.2.3) 2016-01-26 7bee00d OpenJDK 64-Bit Server VM 24.91-b01 on 1.7.0_91-b02 +jit [linux-amd64]

I don't think there is a way to force rehash after the Gem is installed, so I may have to leave this one the way it is.

That worked for me on rbenv.

Now with 9.1.8.0 It is not working again. It can't find the executable, when I find it in the gem directory and execute it I get this:

bin % ./mjruby -S pry
RuntimeError: JRUBY_HOME directory is malformed: no lib directory found!

Not sure what todo. JRUBY_HOME is not defined, btw.
