Both rbenv and ruby-build are generally installed from Github by cloning; That's how <a href="https://github.com/sstephenson/rbenv" rel="noreferrer">the authors recommend we install it</a>. 

<pre><code>git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
</code></pre>

If you didn't do it that way I'd recommend that method. Then, you can simply do:

<pre><code>cd ~/.rbenv
git pull
cd plugins/ruby-build
git pull
</code></pre>

If you have several plugins use:

<pre><code>cd plugins
for i in *
do
 cd $i
 git pull
 cd -
done
</code></pre>

I update every couple weeks just to pull in the latest fixes/changes.

blocks|key|4624066|text|这件事今天发生在我身上。"rbenv+install+-l‘显示过时的列表，而"ruby-build+--definitions“返回正确的列表。通过执行以下命令可以修复此问题：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4624067|rm+-Rf+~/.rbenv/plugins/ruby-build|code-block|syntax|javascript|4624068|似乎在~/.rbenv/plugins下有一个过时的ruby-build版本。不确定它是什么时候生成的。|4624069|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

This happened to me today. "rbenv install -l' displays outdated list while "ruby-build --definitions" returns the correct list. The problem is fixed by executing following command:

<pre><code>rm -Rf ~/.rbenv/plugins/ruby-build

It seems there is an outdated version of ruby-build under ~/.rbenv/plugins. Not sure when it got generated.

<a href="http://ryaneschinger.com/blog/updating-ruby-build/" rel="noreferrer">This link</a>
gives a good explanation of the two available options.

If you installed rbenv from the git repository:
<code>
$ cd ~/.rbenv/plugins/ruby-build
$ git pull
</code>

If you used Homebrew on OSX to install rbenv:
<code>
$ brew update
$ brew upgrade ruby-build
</code>
(Also running <code>brew doctor</code> might give you the exact solution.)

And if you have permission denied errors, this is my addition:
<code>
$ sudo chown -R $USER /usr/local; brew update
$ sudo chown -R $USER /usr/local; brew upgrade ruby-build
</code>

Then you'll be able to install the recent versions.
<code>
$ rbenv install --list
$ rbenv install 2.1.2
</code>

blocks|key|118204|text|选择的答案可以很好地工作，但这个问题可能只是由于自制软件当时没有最新的ruby-build公式造成的。在这篇文章中，适当的ruby构建公式已经被放入了最新版本的自制软件中。所以运行：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|118205|$+brew+update|offset|length|style|CODE|118206|应该会得到你需要的版本来获得最新的ruby。然后，再次运行rbenv+install+--list应该会列出2.1.2+(以及其他)。|118207|因此，如果有人后来看到了这一点，如果您更愿意使用自制软件进行包管理，希望您可以避免维护单独的存储库。|118208|entityMap^0|0|0|D|0|T|K|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@$D|P|E|Q|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|R|8|@$D|S|E|T|F|G]]|9|@]|A|$]]|$1|J|3|K|5|6|7|U|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|M|$]]

The selected answer will work fine, but the issue may have simply been caused by homebrew not having an up-to-date formula for ruby-build at the time. As of this posting, the appropriate ruby-build formula has been put into the latest version of homebrew. So running:

<code>$ brew update</code>

should get you version needed to get the latest ruby. Then, running <code>rbenv install --list</code> again should list 2.1.2 (and others).

So if anyone sees this later on, hopefully you can avoid having to maintain the individual repositories if you'd rather use homebrew for package management.

I've just updated ruby-build and ruby-install to latest versions and both have the latest ruby 2.1.2

Probably rbenv doing something nasty.

blocks|key|4624257|text|在所有这些之后，在OSX+10.11上它仍然不会列出最新版本。我在下面所做的工作对我很有效-我删除了目录，从brew重新安装，然后我必须在brew中像这样链接：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4624258|$+brew+uninstall+ruby-build+--force
$+rm+-Rf+~/.rbenv/plugins/ruby-build|code-block|syntax|javascript|4624259|然后|4624260|$+brew+install+ruby-build
$+brew+link+--overwrite+ruby-build|4624261|然后我看到了要构建的最新版本。|4624262|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Following all the above, on OSX 10.11 it still wouldn't list the latest versions. What I did below worked for me- I removed the dir, re-installed from brew then I had to link in brew like this:

<pre><code>$ brew uninstall ruby-build --force
$ rm -Rf ~/.rbenv/plugins/ruby-build
</code></pre>

and then

<pre><code>$ brew install ruby-build
$ brew link --overwrite ruby-build
</code></pre>

and then I saw the most recent versions to build.

I installed <code>rbenv</code> via Homebrew on an OS X 10.9.3 MacBook Pro:
<pre><code>brew update
brew upgrade rbenv ruby-build
</code></pre>
According to <code>rbenv install --list</code> on my laptop <code>Ruby 2.1.0-dev</code> is the latest.

rbenv install --list does not list version 2.1.2

我在OS X 10.9.3 MacBook专业版上通过Homebrew安装了rbenv：brew updatebrew upgrade rbenv ruby-build据我笔记本电脑上的rbenv install --list介绍，Ruby 2.1.0-dev是最新的。
