如何在 CodeDeploy buildspec 文件上使用 gulp?

How can I use gulp on CodeDeploy buildspec file?

这是我的构建规范文件:

# 0.1 : shell for each command 
# 0.2 : shell keeps its settings
# 
version: 0.2 

phases:
  install:
    commands:
      - echo INSTALL started on `date`
      - cd wp-content/themes/sitecampaign-sage
      - echo `pwd`
      - npm install bower -g
      - npm install grunt -g
      - npm install gulp -g
      - echo INSTALL completed on `date`
  pre_build:
    commands:
      - echo PRE_BUILD started on `date`
      - echo `pwd`
      - bower -v
      - node -v
      - npm -v
      - gulp -v
      - gulp default
      - echo PRE_BUILD completed on `date`
  build:
    commands:
      - echo BUILD started on `date`
      - echo `pwd`
#      - gulp
      - echo BUILD completed on `date`
  post_build:
    commands:
      - echo POST_BUILD started on `date`
      - echo `pwd`
      - rm -rf node_modules
      - rm -rf bower_components
      - echo POST_BUILD completed on `date`
artifacts:
  files:
    - /**/*
  discard-paths: no

但即使 gulp -v returns gulp 版本 正确 、运行 gulpgulp default (gulp ) 说 gulp 没有安装 !????

我错过了什么?有人有同样的问题吗?

忘记了所有关于 运行宁 npm installbower install 的事情......更多地关注工具本身,我忘记了简单地 运行 日常工作日命令...

最终文件规范:

# 0.1 : shell for each command 
# 0.2 : shell keeps its settings
# 
version: 0.2 

phases:
  install:
    commands:
      - echo INSTALL started on `date`
      - cd wp-content/themes/sitecampaign-sage
      - echo `pwd`
      - npm install bower -g
      - npm install grunt -g
      - npm install gulp -g
      - npm install
      - bower install --allow-root
      - echo INSTALL completed on `date`
  pre_build:
    commands:
      - echo PRE_BUILD started on `date`
      - echo `pwd`
      - bower -v
      - node -v
      - npm -v
      - gulp -v
      - which gulp
      - echo PRE_BUILD completed on `date`
  build:
    commands:
      - echo BUILD started on `date`
      - echo `pwd`
      - which gulp
      - gulp default
      - echo BUILD completed on `date`
  post_build:
    commands:
      - echo POST_BUILD started on `date`
      - echo `pwd`
      - rm -rf node_modules
      - rm -rf bower_components
      - echo POST_BUILD completed on `date`
