Drone CI 找不到 100% 肯定存在的 Node 模块

问题描述

我的项目是一个用 gulp 编译的非常简单的网站。

Gulp：

• PostCSS -> CSS;和
• 帕格-> HTML；和
• 一些图像大小调整

没有什么太令人震惊的。它在我的机器上运行。它在我的另一台机器上运行。没有汗水。一切都很好。

它曾经在 Travis CI 上运行（在我用完学分之前 :( ）。所以我安装了 Drone CI。一切正常，它正在做它应该做的事情，除了实际构建我的项目。

npm i 运行良好。我在之后立即执行的 node_modules 中看到 ls。 但是当我然后运行 ​​npm run build（本身只是 gulp build - gulp 包含在 package.json 的依赖项字段中）时，Drone 输出此错误：

+ npm run build

> tribute-page@0.0.0 build /drone/src
> gulp build

这是我的 .drone.yml：

---
kind: pipeline
type: docker
name: default

clone:
  depth: 2

steps:
  - name: install
    image: node:14
    volumes:
      - name: nodemod
        path: /node_modules
    pull: if-not-exists
    commands:
      - npm i
      - ls
    environment:
      NODE_ENV: production

  - name: cry
    privileged: true
    image: node:14
    volumes:
      - name: nodemod
        path: /node_modules
    commands:
      - echo "You heard me. Start sobbing."
      - npm run build
    environment:
      NODE_ENV: production

volumes:
  - name: nodemod
    temp: {}

和我的 package.json（名称、作者和 repo 已删除）：

{
  "version": "0.0.0","description": "a tribute to... some guy","main": "main.js","license": "MIT","private": true,"type": "commonjs","devDependencies": {

  },"browserslist": [
    "defaults","not IE 11","maintained node versions"
  ]
}

我不明白。搜索引擎没有太大帮助，它们都提到了 Dockerfile 特定的东西，而且，由于我在这里不处理 Dockerfile，所以它没有多大用处。

有什么想法吗？

解决方法

史诗！

事实证明设置 NODE_ENV=production 会使 npm 忽略 devDependencies。从 .drone.yml 中删除它以获得这样的步骤：

 - name: cry                                                                                                                                    
   privileged: true                                                                                                                             
   image: node:14                                                                                                                               
   volumes:                                                                                                                                     
     - name: nodemod                                                                                                                            
       path: /node_modules                                                                                                                      
   commands:                                                                                                                                    
     - echo "You heard me. Start sobbing."                                                                                                      
     - npm run build      

现在说得通了。谢谢@David784！
