I need to update my ruby version from 2.0.0 to the latest version, I can not use some gems because my version is not updated. 我需要将红宝石版本从2.0.0更新到最新版本，因为我的版本未更新，所以我无法使用某些gems。 I had used Homebrew to install Ruby some time ago, How can i update my Ruby version? 我之前曾经用Homebrew安装Ruby，如何更新Ruby版本？

Open your terminal and run 打开终端并运行 

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

When this is complete, you need to restart your terminal for the rvm command to work. 完成此操作后， 需要重新启动终端才能使rvm命令起作用。

Now, run rvm list known 现在，运行rvm list known

This shows the list of versions of the ruby. 这显示了红宝石的版本列表。

Now, run rvm install [email protected] to get the latest ruby version. 现在，运行rvm install [email protected]以获取最新的ruby版本。

If you type ruby -v in the terminal, you should see ruby XXX . 如果在终端中输入ruby -v ，应该会看到ruby XXX 。

If it still shows you ruby 2.0. 如果仍然显示ruby 2.0. , run rvm use ruby-XXX --default . ，运行rvm use ruby-XXX --default 。

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? *如果这符合您的条件： https : //github.com/rbenv/rbenv/wiki/为什么使用rbenv？ : ：

rbenv does… rbenv 确实...

  • Provide support for specifying application-specific Ruby versions . 提供对指定特定于应用程序的Ruby版本的支持 。
  • Let you change the global Ruby version on a per-user basis. 让您按用户更改全局Ruby版本 。
  • Allow you to override the Ruby version with an environment variable. 允许您使用环境变量覆盖Ruby版本 。

In contrast with RVM, rbenv does not… 与RVM相比，rbenv 不…

  • Need to be loaded into your shell. 需要加载到您的外壳中。 Instead, rbenv's shim approach works by adding a directory to your $PATH . 而是rbenv的shim方法通过将目录添加到$PATH 。
  • Override shell commands like cd or require prompt hacks. 覆盖诸如cd类的shell命令，或要求立即进行**。 That's dangerous and error-prone. 这很危险，而且容易出错。
  • Have a configuration file. 有一个配置文件。 There's nothing to configure except which version of Ruby you want to use. 除了要使用哪个版本的Ruby，没有其他配置。
  • Install Ruby. 安装Ruby。 You can build and install Ruby yourself, or use ruby-build to automate the process. 您可以自己构建和安装Ruby，也可以使用ruby-build自动化该过程。
  • Manage gemsets. 管理宝石集。 Bundler is a better way to manage application dependencies. Bundler是管理应用程序依赖项的更好方法。 If you have projects that are not yet using Bundler you can install the rbenv-gemset plugin. 如果您有尚未使用Bundler的项目，则可以安装rbenv-gemset插件。
  • Require changes to Ruby libraries for compatibility. 需要更改Ruby库以获得兼容性。 The simplicity of rbenv means as long as it's in your $PATH , nothing else needs to know about it. 只要它在你的rbenv手段简单$PATH ， 没有什么 别的需要了解它。
