(LoadError) on getting version out of gem cache #21

nmccready · 2013-06-19T21:27:18Z

custom_require.rb:60:in `require': cannot load such file -- version (LoadError)

Is produced by:

ruby-1.9.3-p429/
rvm 1.21.1 (stable)
rspec 2.13.1 .

It seems that the loader is confused with loading version/ or version.rb. Stating 'require version.rb' explicitly fixes the issue as the work around.

Ruby does not ever attempt to require directories. Without more information, I have no way to debug this. Where and how are you doing require 'version'? Are you using bundler? What is the entire stack trace? What are the contents of your $LOAD_PATH?

nmccready · 2013-06-20T02:20:57Z

I am just trying to get this working with a basic ruby application before I troubleshoot a larger app. I am not using bundler that I know of. To me there seems to be an issue with RVM and it not linking gems path correctly.

I ran "irb" and 'require version' failed until I put 'require rubygems' first. I hope this helps. Sorry I am new to this.

The stack below happened when rspec spec/ was called against.

This is expected, correct behavior. If you have installed a gem via rubygems, you must require rubygems before you can use it.

nmccready · 2013-06-20T11:33:36Z

I have loaded the gem via gem install version. The gem is installed as far as I van tell "gem list | grep version" => version 1.0.0. . At the gem directory is code that matches github. I am here because this is the first gem that is not loading for me. My next step is to blow away rvm and reinstall ruby.

stouset · 2013-06-20T12:37:54Z

As you have described it, this is not a bug in version. Sorry. If you are using gems, you must require rubygems in your application before requiring the individual gems themselves.

nmccready · 2013-06-20T12:39:07Z

I just reinstalled ruby with the default rvm installation. I am using
2.0.0-p195 and the same error exists.

Should gems be in my $PATH besides rvm magic?

nmccready · 2013-06-20T12:44:07Z

The rspec version requirement is ~> '1' will rspec's greater than '1' not work correctly?

nmccready · 2013-06-20T13:08:58Z

I cloned sodium and got all your tests to pass via "rake test".

I added a spec/get_version_spec.rb

require 'sodium/version'

describe "Version should" do
  subject do
    Sodium::VERSION
    end

  describe "version" do
    it "extracts version" do
      subject.should == "0.5.0"
    end
  end
end

Failed on rspec spec!

To me this has to be an issue with rspec.

I'm sorry, but this appears to be a configuration issue with your local environment.

I know this is closed, but this is still bugging me. Is this possibly relevant? http://stackoverflow.com/questions/11499140/weird-loaderror-on-custom-ruby-gem

nmccready · 2013-06-20T19:34:22Z

This issue has to be due to rspec version 1 being required. I cannot even get the specs of this application to run via rspec 2. So I can't use this library unless I can get both rspecs to work side by side.

stouset · 2013-06-20T19:59:30Z

Do you have the mail gem installed? It is a dependency of Rails.

stouset · 2013-06-20T20:05:07Z

The mail gem is being a bad Ruby citizen by having a file named VERSION not placed under its directory namespace. A workaround for now is to call

gem     'version'
require 'version'

which will force the gem to be activated.

nmccready · 2013-06-20T20:08:02Z

I fam working on the fix. I have upgraded version to rspec 2. That is the problem. I now have all specs working with the changes. Weird thing is the gemspec should have failed on gem install as the version of rspec that version-1.0.0 needs is not there.

nmccready · 2013-06-20T20:18:50Z

gem list | grep mail
actionmailer (3.2.13)
mail (2.5.4)

Ahh The mail gem is being a bad Ruby citizen by having a file named VERSION.....

Thats why my copy of version 1.1.0a is not working either.

nmccready · 2013-06-20T20:22:05Z

Both gem 'version' and uninstalling mail fixes the issue. Do you want me to do a pull request for rspec upgrade?

stouset · 2013-06-20T20:31:40Z

Why?

The gem is effectively complete, and switching to rspec 2 would gain little if anything. It's also a development dependency, so it's not a requirement to install the gem and won't cause conflict with projects that require rspec 2 or newer.

nmccready · 2013-06-20T20:39:28Z

If thats true then no big deal. It's just majorly confusing when your
trying to figure out what's wrong and that is what did not match up. How
did you figure out mail btw?
