I’m trying to install a jruby 1.5.1 on a fresh system using rvm… here
is the commad

rvm install jruby-1.5.1
–with-openssl-dir=/usr/local/rvm/usr,–with-readline-dir=/usr/local/rvm/usr

I need to install jruby-1.5.1 before installing any other gems. But i
get this error saying it needs the rake gem!

…
/usr/local/rvm/rubies/jruby-1.5.1/bin/jruby -S rake
/usr/local/rvm/rubies/jruby-1.5.1/lib/ruby/site_ruby/1.8/rubygems.rb:777:in
report_activate_error': Could not find RubyGem rake (>= 0) (Gem::LoadError) from /usr/local/rvm/rubies/jruby-1.5.1/lib/ruby/site_ruby/1.8/rubygems.rb:211:inactivate’
from
/usr/local/rvm/rubies/jruby-1.5.1/lib/ruby/site_ruby/1.8/rubygems.rb:1056:in
`gem’
from /usr/local/rvm/rubies/jruby-1.5.1/bin/rake:18
make: *** [test] Error 1

Seem like a catch-22, need jruby-1.5.1 before i can install rake, but
jruby-1.5.1. need rake to install!

Thanks for any insights.

Roger, thanks for the pointers. I’ll have to keep looking.

I’m using capistrano to spin up new instances in aws… I have to do a
weird scripts to intall it.

  1. rvm install jruby-1.5.1 …
  2. gem install rake
  3. gem install rspec
  4. rvm install jruby-1.5.1 …

Apparently, after install rake. It dies on “rspec gem not found”.

Finally, when the jruby is installed, it added the gem ruby-launcher as
part of the basic install.
