将Rails升级到最新版本

Question

I'm new to the Ruby on Rails environment and would like to get input in relation to upgrading my Rails environment from 4.0.2 to 4.2.3, which I assume is the latest version. 我是Ruby on Rails环境的新手，并且想获得有关将Rails环境从4.0.2升级到4.2.3的信息，我认为这是最新版本。

My Ruby version is 2.0.0p353 (2013-11-22) [i386-mingw32] . 我的Ruby版本是2.0.0p353 (2013-11-22) [i386-mingw32] 。

Is upgrading a straight-forward process? 升级是否简单明了？ If not, what is the upgrade path I need to follow? 如果没有，我需要遵循的升级路径是什么？
I normally use bundle install cmd to install all gems. 我通常使用bundle install cmd安装所有gem。 Is there a similar command to upgrade to the latest version? 是否有类似的命令可以升级到最新版本？
Do I need to backup my apps before I try anything? 在尝试任何操作之前，是否需要备份我的应用程序？

Answer 1

In your gemfile change: 在您的gemfile中更改：

gem 'rails', '4.0.2'

to 至

gem 'rails', '4.2.3'

and in your terminal run bundle update . 并在终端中运行bundle update 。

If you are trying to update ONLY Rails, run: bundle update rails . 如果您尝试仅更新Rails，请运行： bundle update rails 。
