Open your terminal and run

打开你的终端并运行

curl -sSL https://raw.githubusercontent.com/rvm/rvm/master/binscripts/rvm-installer | bash -s stable

When this is complete, you need to restart your terminalfor the rvmcommand to work.

完成后，您需要重新启动终端以使rvm命令生效。

Now, run rvm list known

现在，运行 rvm list known

This shows the list of versions of the ruby.

这显示了 ruby​​ 的版本列表。

Now, run rvm install ruby@latestto get the latest ruby version.

现在，运行rvm install ruby@latest以获取最新的 ruby​​ 版本。

If you type ruby -vin the terminal, you should see ruby X.X.X.

如果您ruby -v在终端中输入，您应该会看到ruby X.X.X.

If it still shows you ruby 2.0., run rvm use ruby-X.X.X --default.

如果它仍然显示您ruby 2.0.，请运行rvm use ruby-X.X.X --default。

Brew only solution

只酿造解决方案

Update:

更新：

From the comments (kudos to Maksim Luzik), I haven't tested but seems like a more elegant solution:

从评论（对 Maksim Luzik 的称赞），我还没有测试过，但似乎是一个更优雅的解决方案：

After installing ruby through brew, run following command to update the links to the latest ruby installation: brew link --overwrite ruby

通过 brew 安装 ruby​​ 后，运行以下命令以更新最新 ruby​​ 安装的链接： brew link --overwrite ruby

Original answer:

原答案：

Late to the party, but using brew is enough. It's not necessary to install rvm and for me it just complicated things.

聚会迟到了，但使用 brew 就足够了。没有必要安装 rvm，对我来说它只是复杂的事情。

By brew install rubyyou're actually installing the latest (currently v2.4.0). However, your path finds 2.0.0 first. To avoid this just change precedence (source). I did this by changing ~/.profileand setting:

通过brew install ruby你在实际安装最新版本（V2.4.0目前）。但是，您的路径首先找到 2.0.0。为了避免这种情况，只需更改优先级（source）。我通过更改~/.profile和设置来做到这一点：

export PATH=/usr/local/bin:$PATH

export PATH=/usr/local/bin:$PATH

After this I found that bundler gem was still using version 2.0.0, just install it again: gem install bundler

在此之后我发现 bundler gem 仍在使用版本 2.0.0，只需再次安装它： gem install bundler

I recommend rbenv* https://github.com/rbenv/rbenv

我推荐rbenv* https://github.com/rbenv/rbenv

* If this meets your criteria: https://github.com/rbenv/rbenv/wiki/Why-rbenv?:

* 如果这符合您的标准：https: //github.com/rbenv/rbenv/wiki/Why-rbenv? ：

rbenv does…

• Provide support for specifying application-specific Ruby versions.
• Let you change the global Ruby versionon a per-user basis.
• Allow you to override the Ruby versionwith an environment variable.

In contrast with RVM, rbenv does not…

• Need to be loaded into your shell.Instead, rbenv's shim approach works by adding a directory to your $PATH.
• Override shell commands like cdor require prompt hacks.That's dangerous and error-prone.
• Have a configuration file.There's nothing to configure except which version of Ruby you want to use.
• Install Ruby.You can build and install Ruby yourself, or use ruby-buildto automate the process.
• Manage gemsets.Bundleris a better way to manage application dependencies. If you have projects that are not yet using Bundler you can install the rbenv-gemsetplugin.
• Require changes to Ruby libraries for compatibility.The simplicity of rbenv means as long as it's in your $PATH, nothingelseneeds to know about it.

rbenv确实…

• 为指定特定于应用程序的 Ruby 版本提供支持。
• 让您在每个用户的基础上更改全局 Ruby 版本。
• 允许您使用环境变量覆盖 Ruby 版本。

与 RVM 相比，rbenv不......

• 需要加载到你的shell中。相反，rbenv 的 shim 方法通过将目录添加到您的$PATH.
• 覆盖 shell 命令，例如cd或需要提示 hacks。这很危险，而且容易出错。
• 有配置文件。除了要使用的 Ruby 版本之外，无需配置任何内容。
• 安装红宝石。您可以自己构建和安装 Ruby，或者使用ruby-build来自动化该过程。
• 管理宝石。Bundler是管理应用程序依赖关系的更好方法。如果您有尚未使用 Bundler 的项目，您可以安装 rbenv-gemset插件。
• 需要更改 Ruby 库以实现兼容性。只要它在你的rbenv手段简单$PATH， 没有什么别的需要了解它。
