使用rbenv无法找到正确的红宝石版本？

Question

I am working in OSX El Capitan. I have put the following at the end of my ~/.bash_profile , and restarted my terminal:

export RBENV_ROOT=/usr/local/var/rbenv
if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi

Then I have run the following, without any errors:

brew install rbenv
brew install ruby-build
rbenv install 2.2.2

But when I try ruby --version I see:

ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin15]

What am I doing wrong that means I see Ruby 2.0.0 not Ruby 2.2.2?

These are my paths:

~ $ which ruby
/usr/local/var/rbenv/shims/ruby
~ $ which rbenv
/usr/local/bin/rbenv

我认为您必须通过以下方式更改ruby版本：

rbenv shell 2.2.2
