Enabling hook (one time)
rvm get head && rvm reload
chmod +x $rvm_path/hooks/after_cd_bundler
Generating bundler stubs (binaries wrappers)
cd /path/to/project
bundle install --binstubs
With RVM integration enabled, the bin directory is added to your path each time you cd into a project directory with binstubs. That means you can just run rake. If you aren’t ignoring the bin directory in your project, you should do so:
# .gitignore
bin/
Now, you don’t have to type “bundle exec” again.
