rbenv & ruby-build not showing the same list of version

问题

I'm trying to install the latest ruby version (ie. 2.1.1) with rbenv.

After upgrading brew, ruby-build and rbenv the available ruby versions differs.

Executing:

ruby-build --definitions

gives me (only versions above 2.0):

2.0.0-dev
2.0.0-p0
2.0.0-p195
2.0.0-p247
2.0.0-p353
2.0.0-p451
2.0.0-preview1
2.0.0-preview2
2.0.0-rc1
2.0.0-rc2
2.1.0
2.1.0-dev
2.1.0-preview1
2.1.0-preview2
2.1.0-rc1
2.1.1
2.2.0-dev

With RBenv:

rbenv install -l 

gives me (only versions above 2.0):

2.0.0-dev
2.0.0-p0
2.0.0-p195
2.0.0-p247
2.0.0-p353
2.0.0-preview1
2.0.0-preview2
2.0.0-rc1
2.0.0-rc2
2.1.0-dev
2.1.0-preview1
2.1.0-preview2

What is happening here ?

回答1:

Have you updated rbenv and the rbenv-build plugin to the latest versions?

I personally prefer doing that by browsing to their installation folders (~/.rbenv and ~/.rbenv/plugins/ruby-build) and pulling the latest changes, as in:

git pull origin master

I personally see all rubies when asking for a list (including 2.1.1).
