I have a bit of a chicken & egg problem:
Assume I have a top level directory for all my Rails projects. Each project might be using a different version of Ruby and Rails.
How do I run a “rails new foo” with the correct ruby version and gemset?
Is there some sort of cmd line argument I can use?
-joe
rvm use version@gemset
You could also create a custom .rvmrc file for each project folder, in which you could specify the ruby version and gemset to use (or create if doesn’t exist’).
How do I run a "rails new foo" with the correct ruby version and gemset?

rails _4.1.10_ new
Should invoke that version of the rails executable (this is a rubygems thing - it should work with any executable provided by a gem.

I always begin new rails projects by first creating the project directory
$ mkdir foo
$ cd foo/
$foo/
Once in the directory I make a .ruby-version and .ruby-gemset file
$foo/ touch .ruby-version .ruby-gemset
In the ruby-version file you just specify the version of ruby you wish to use
2.2.1
and the ruby-gemset file you name the gemset you’d like to use
fooapp
Once you have those saved you can reload the current directory by
$foo/ cd .
Then just rails new . and then bundle install
