bundle update seems to be deleting my .gem file

Question

I am new to building gems, so bear with me.

Scenario:

[Gemfile]
source 'https://rubygems.org'
gem 'curriculous', path: '/mydev/curriculous'

---

$ ls /mydev/curriculous
Gemfile             Rakefile            curriculous.sublime-project
Gemfile.lock            bin             curriculous.sublime-workspace
LICENSE.txt         curriculous-0.0.1.alpha.gem lib
README.md           curriculous.gemspec     spec

---

$ bundle update

Question: where did my .gem file go? What am I doing wrong?

Addendum 1

• The gemfile above is in my testfile. I've uploaded it to github: https://github.com/pitosalas/testcur
• The gem itself is also now on github: https://github.com/pitosalas/curriculous

• The version of gem (gem -v) is 2.0.2

• I admit again that I've not done this before so I probably have something totally boneheaded that I am doing.

• I think I am trying to do something a little tricky and there might be a much better way to do it too
• But this weird behavior of the .gem file being deleted doesn't fit any of my mental models of gems and so on that I would like to track down what is going on.

Answer 1

Is the Gemfile that you're showing the one inside curriculous itself, or a second project that uses curriculous?

If it's the one inside curriculous, then you should remove the gem 'curriculous', path: '/mydev/curriculous' line. That indicates that curriculous depends on itself, which is probably not what you mean :)

Instead, add a line that has only gemspec. This tells Bundler to read the curriculous.gemspec file to find the dependencies for the project.

There's a basic tutorial for creating gems at http://net.tutsplus.com/tutorials/ruby/gem-creation-with-bundler/

If that Gemfile is for a different project, then you're doing it correctly. Is there something that isn't working? Running bundle will rebuild the gem. The specifics of what it does depends on what version of RubyGems is active. Can you post gem --version?
