Ruby 3.0 is not supported yet (see [the relevant epic](https://gitlab.com/groups/gitlab-org/-/epics/5149) for the current status). You must use the standard MRI implementation of Ruby. We love [JRuby](https://www.jruby.org/) and [Rubinius](https://github.com/rubinius/rubinius#the-rubinius-language-platform), but GitLab needs several Gems that have native extensions. |

 | [Node.js](#4-node) | `12.22.1` | GitLab uses [webpack](https://webpack.js.org/) to compile frontend assets. Node.js 14.x is recommended, as it's faster. You can check which version you're running with `node -v`. You need to update it to a newer version if needed. |
