Bundling local gem (that I'm developing) does not seem to include lib directory (using rvm)

Question

I'm trying to develop a gem locally, and have installed it with Bundler.

My Gemfile looks like this:

source "http://rubygems.org"
gemspec

And my gemspec is a standard gemspec file.

I can install the gem with 'bundle install' in the directory, and i see the local gem and all it's dependencies install:

bundle install
Using rack (1.3.4) 
Using tilt (1.3.3) 
Using sinatra (1.3.1)  
Using {my gem} (0.0.2) from source at . 
Using bundler (1.0.21) 
Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

However, when I do a 'gem list', my gem is not included in the list of gems - which is my guess as to why my bin directory does not appear in the path. Is there a way to test a local gem and include it in the list of installed gems using bundler, so that the bin directory properly works?

Answer 1

Easiest way to get rid of bundler: command not found: {your bin executable}:

git add bin/*  # git-ls-files will now list your bin executables.
bundle install 
# No git-commit necessary.
bundle exec <MY_BIN_EXECUTABLE>

Answer 2

gem list shows your system installed gems, not the gems in your Bundle (this are often the same but not always--as in this case). When you're using Bundler, you should always execute gem executables with bundle exec so that Bundler can set up the environment for you. So, if you have a binary called, for example, mygem, you should use bundle exec mygem.

See more info at Bundler's site or in the manpage.

[Edit]

Also be sure that your gemspec includes a bin directory! Common convention is to create a directory called bin at the same level as your lib directory, put your binaries in there, and then add this as the directory in your gemspec. If you don't do this, Bundler won't expose your binaries!

Answer 3

I had this problem too.

Make sure the executables and default_executable lines don't contain 'bin/'. Then:

git add add . # You can be more precice if you want.
git commit -m "My lousy commit message."
bundle install
bundle exec <binaryname>
