RubyGems mysteriously broken (paths issue?

elektrophyte

9/1/2007 2:55:00 AM

Just installed RubyGems 0.9.0 on Ubuntu 7.04. I ran gem install rails
and it said that it worked successfully.

But tried to run "rails mynewapp" and got "bash: rails: command not
found".

Ran...

# gem list -l rails

*** LOCAL GEMS ***

rails (1.2.3)
Web-application framework with template engine, control-flow
layer,
and ORM.

So the rails gem was installed. I tried...

# gem contents rails
Unable to find gem 'rails' in default gem paths

So gem list rails works, but gem contents rails doesn't work.

So I checked what gem thinks its environment is...

# gem environment
Rubygems Environment:
- VERSION: 0.9.0 (0.9.0)
- INSTALLATION DIRECTORY: /var/lib/gems/1.8
- GEM PATH:
- /var/lib/gems/1.8
- REMOTE SOURCES:
- http://gems.rub...

/var/lib/gems/1.8 actually does contain "bin/" "cache/" "doc/" "gems/"
"source_cache" "specifications/". Within that, the gems/ dir does
indeed contain dirs for all the gems I've just installed such as
rails, actionmailer, mongrel, and several others.

Any help to fix this would be greatly appreciated.

Thanks.

Please remove the rubygems package that you installed using apt-get,
its broken. Download the tgz file of rubygems from rubyforge.org and
install rubygems using that. Everything will be fine after that.

Yes, that corrected the problem. Thanks.

RubyGems 0.9.0 has a security exploit. 0.9.4 is the latest.
