Question

I ahve rbenv installed with Ruby 1.9.3-p374 and I gem installed bundler.

I then set up a project diretory and set a .ruby-version file within to choose my 1.9.3 ruby version and then added a gemfile with some gems like compass etc. I then ran bundle install --path vendor and it installed.

If I then run bundle show I get this:

Gems included by the bundle:
  * bundler (1.2.3)
  * chunky_png (1.2.7)
  * compass (0.12.2)
  * fssm (0.2.10)
  * sass (3.2.5)
  * susy (1.0.5)

and if I run gem list I get this:

*** LOCAL GEMS ***

bigdecimal (1.1.0)
bundler (1.2.3)
io-console (0.3)
json (1.5.4)
minitest (2.5.1)
rake (0.9.2.2)
rdoc (3.9.4)

How do I get them to all work together. I want the local project gems like compass etc to be installed into the vendor directory like they are but when I cd into my project directory and run a compass watch command I get -bash: compass: command not found

Why is it not working?

Answer 1

When running gems from your vendor bundle (instead of local gems), you should use bundle exec:

~/project$ bundle exec compass watch

If you want to run Compass directly, you’ll have to install it on your system (local gems) using either vanilla bundle install or simply gem install compass. (In that case, you might sometimes run into a conflict of gem versions, Gemfile vs. called from system)
