Gitlab CI设置错误 - 找不到JavaScript运行时

I am trying to setup Gitlab CI for my Ruby on Rails project, but ran into an error that I don't know how to fix.

我正在尝试为我的Ruby on Rails项目设置Gitlab CI，但遇到了一个我不知道如何解决的错误。

The application is running on Ruby 2.3.1, Rails 5.0 and is using a postgreSQL database.

该应用程序在Ruby 2.3.1，Rails 5.0上运行，并使用postgreSQL数据库。

My current .gitlab.ci.yml file looks like this:

我当前的.gitlab.ci.yml文件如下所示：

# https://hub.docker.com/r/library/ruby/tags/
image: "ruby:2.3.0"

# Pick zero or more services to be used on all builds.
# Only needed when using a docker container to run your tests in.
# Check out: http://docs.gitlab.com/ce/ci/docker/using_docker_images.html#what-is-service
services:
  - redis:latest
  - postgres:latest
  - node:latest

# This is a basic example for a gem or script which doesn't use
# services such as redis or postgres
before_script:
  - gem install bundler         # Bundler is not installed with the image
  - bundle install -j $(nproc)  # Install dependencies

rubocop:
  script:
  - rubocop

rspec:
  script:
  - rspec spec

rails:
  script:
  - rails db:migrate
  - rspec spec

So it's supposed to be using NodeJS as runtime. However, I get the following error:

所以它应该使用NodeJS作为运行时。但是，我收到以下错误：

$ rails db:migrate
rails aborted!

You need javascript runtime (nodejs), install them.

你需要javascript运行时（nodejs），安装它们。

Ubuntu Users

Ubuntu用户

sudo apt-get install nodejs

CentOS/RedHat Users

CentOS / RedHat用户

sudo yum install nodejs

If you can't install nodejs you can use therubyracer gem. Description from repository:

如果你不能安装nodejs你可以使用therubyracer gem。存储库中的描述：

Embed the V8 JavaScript interpreter into Ruby.

将V8 JavaScript解释器嵌入到Ruby中。

Add this lines to Gemfile

将此行添加到Gemfile

gem 'therubyracer', platforms: :ruby
