gitlab CI - 安装正确版本的 yarn

Question

我正在尝试使用 gitlab 设置 CI/CD，但我在特定时刻卡住了。下面是我的 .gitlab-ci.yml 文件：

image: "ruby:2.6"

before_script:
  - ruby -v
  - apt-get update -qy
  - apt-get install -y nodejs
  - apt-get install -y yarn
  - yarn --version
  - bundle install --path /cache
  - bundle exec rails webpacker:install

test:
  script:
    - bundle exec rake db:create RAILS_ENV=test
    - bundle exec rake test

CI 输出无错误地进行，直到它达到 $ bundle exec rails webpacker:install。任务中止并显示此消息：

$ bundle exec rails webpacker:install
rails aborted!
ArgumentError: Malformed version number string 0.32+git
/builds/kvinklly/sample-app/bin/rails:5:in `<top (required)>'
/builds/kvinklly/sample-app/bin/spring:8:in `require'
/builds/kvinklly/sample-app/bin/spring:8:in `block in <top (required)>'
/builds/kvinklly/sample-app/bin/spring:5:in `tap'
/builds/kvinklly/sample-app/bin/spring:5:in `<top (required)>'
Tasks: TOP => webpacker:install => webpacker:check_yarn
(See full trace by running task with --trace)

我注意到 0.32+git 值很可能是安装的 yarn 版本，并验证了该版本：

$ yarn --version
0.32+git

有没有办法在 gitlab 上的 CI 脚本中指定较新版本或最新版本的 yarn？

我可以 post gemfile，但它是一个相当基本的 rails 应用程序，此时没有添加太多内容。

我使用以下方法让它工作：

# Official language image. Look for the different tagged releases at:
# https://hub.docker.com/r/library/ruby/tags/
image: "ruby:2.6"

# This is a basic example for a gem or script which doesn't use
# services such as redis or postgres
before_script:
  - ruby -v  # Print out ruby version for debugging
  - curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
  - echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list
  - apt-get update -qy
  - apt-get install -y nodejs
  - apt-get install -y yarn
  - yarn install --check-files
  - bundle install --path /cache  # Install dependencies into ./vendor/ruby
  - bundle exec rake webpacker:install

test:
  stage: test
  script:
    - bundle exec rake db:create RAILS_ENV=test
    - bundle exec rake test
