rbenv 命令行 gems 设置与系统安装

Question

I am using the chef rbenv recipe ( https://github.com/fnichol/chef-rbenv ), doing a system wide install (goes into /usr/local/rbenv) with the rails lastmile cookbook ( https://github.com/DanThiffault/rails-lastmile ). The server works fine, I can install gems, but command line gems don't seem to work ( valkyrie , mysql2psql ).

Do I need to do additional work to get this working?

Answer 1

You have to run rbenv rehash everytime you install a gem with a command line script when using rbenv.

If you installed the gems in a bundle and are running the command from within the directory where the Gemfile is located, @riley's suggestion might be enough. Otherwise, rehash is the command that will make the executables available on the path.

Answer 2

I'm new to rbenv from rvm where it just seemed to work. It looks like in rbenv you have to run :

bundle exec gemxx

Or generate binstubs:
