Question

I have been trying all day to get app-engine sdk to work nothing has really shaped up .

I emptied a gemset and installed google-appengine gem by executing

sudo gem install google-appengine

I have the following gems installed

[gdev@vbox-gdev GAE]$ sudo gem list
Password: 

*** LOCAL GEMS ***

appengine-apis (0.0.24)
appengine-rack (0.0.13)
appengine-sdk (1.4.3)
appengine-tools (0.0.17)
bundler08 (0.8.5)
google-appengine (0.0.21)
jruby-jars (1.5.6)
jruby-rack (1.0.4)
rack (1.3.5)
rubyzip (0.9.4)
[gdev@vbox-gdev GAE]$ 

and as mentioned in this tutorial (http://code.google.com/p/appengine-jruby/wiki/GettingStarted)
I am using CRuby instead of Jruby

[gdev@vbox-gdev GAE]$ ruby -v
ruby 1.9.3p0 (2011-10-30 revision 33570) [i686-linux]

I am getting an error in the first step itself

[gdev@vbox-gdev GAE]$ appcfg.rb generate_app hello
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': iconv will be deprecated in the future, use String#encode instead.
=> Generating gemfile
/usr/lib/ruby/gems/1.9.1/gems/appengine-tools-0.0.17/lib/appengine-tools/gem_bundler.rb:63: warning: already initialized constant RUBY_ENGINE
=> Bundling gems
ERROR:  While executing gem ... (RuntimeError)
    Unknown command bundle
[gdev@vbox-gdev GAE]$ 

Installing bundler(either version 1.0.21 or 0.8) throws the same error .

Any suggestions on solving this ?

PS: I am using arch linux on a virtualbox

First of all you should stick to Ruby 1.8.7. 1.9.x never really took off on appengine-jruby, although it’s possible. Moreover you should use Rubygems 1.3.7.

My local gems are these:

appengine-rack (0.0.13)
appengine-sdk (1.4.3)
appengine-tools (0.0.17)
bundler (1.0.21)
bundler08 (0.8.5)
google-appengine (0.0.21)
haml (3.1.4)
jruby-jars (1.5.6)
jruby-rack (1.0.4)
rack (1.4.0)
rubyzip (0.9.5)
sass (3.1.12)

But guess what, except for the google-appengine gem those aren’t really important. Much much more important is this: ls .gems/bundler_gems/jruby/1.8/gems:

addressable-2.2.7              extlib-0.9.15        multipart-post-1.1.5
appengine-apis-0.0.22          faraday-0.7.6        oauth2-0.5.2
appengine-rack-0.0.12          haml-3.1.4           rack-1.2.1
Basaah-pony-gae-0.2.1          jruby-jars-1.5.6     rack-flash-0.1.2
bouncy-castle-java-1.5.0146.1  jruby-openssl-0.7.2  sass-3.1.15
dm-appengine-0.0.9             jruby-rack-1.0.5     sinatra-1.2.7
dm-core-0.10.2                 json_pure-1.6.5      tilt-1.3.3
dm-validations-0.10.2          multi_json-1.1.0

That at least will give you an easy start. (You can configure the version in the Gemfile)

By the way, good that you use Linux.
