更新package.json时,只在GitLab CI中进行'npm install'

Question

我正在使用GitLab CI进行项目,该过程的第一步是npm install.我node_modules稍后缓存以便更快地运行相同的作业,并将它们定义为构建工件,以便在后续阶段使用它们.但是,即使我缓存node_modules并且它是最新的,npm install每次install_packages运行作业时调用都需要很长时间,因为命令会遍历所有package.json并检查包的更新等(我假设).

根据某些条件,有没有办法只npm install在install_packages工作中运行？更具体地说(我认为这是最好的解决方案),package.json自上次构建以来是否已经改变了？

以下是我的.gitlab-ci.yml文件的相关部分:

image: node:6.9.1

stages:
  - install
  - prepare
  - deploy

install_packages:
  stage: install
  script:
    - npm prune
    - npm install
  cache:
    key: ${CI_BUILD_REF_NAME}
    paths:
      - node_modules/
  artifacts:
    paths:
      - node_modules/
  only:
    - master
    - develop

build_and_test:
  stage: prepare
  script:
    #do_stuff...

deploy_production:
  stage: deploy
  #do_stuff...

deploy_staging:
  stage: deploy
  #do_stuff...

只需使用only:changes标志文档

该工作将是：

install_packages:
  stage: install
  script:
    - npm prune
    - npm install
  cache:
    key: ${CI_COMMIT_REF_NAME}
    paths:
      - node_modules/
  artifacts:
    paths:
      - node_modules/
  only:
    refs:
      - master
      - develop
    changes:
      - package.json

还有一点是：你设置缓存的方式正确吗？阅读此内容： https: //docs.gitlab.com/runner/configuration/autoscale.html#distributed-runners-caching https://docs.gitlab.com/ee/ci/caching/
