docker - 在 docker : Fatal error: Unable to find local grunt 中运行 grunt 时出错

Question

我正在尝试使用 docker 中的所有依赖项运行我的项目，但我遇到了 grunt 依赖项，由于某种原因 grunt 失败，并显示无法找到本地 grunt 的错误。

我创建了一个如何重现此示例的示例:

.
├── code
│   ├── bower.json
│   ├── Gruntfile.js
│   └── package.json
├── docker-compose.yml
└── frontend.dockerfile

docker-compose.yml :

version: "2"
services:
  frontend:
    build:
      context: .
      dockerfile: frontend.dockerfile
    ports:
      - "8585:8000"
    volumes:
      - ./code:/srv/frontend
    command: grunt

前端.dockerfile :

FROM node:wheezy

ADD code /srv/frontend
WORKDIR /srv/frontend
RUN npm install -g grunt-cli bower
RUN npm install

RUN groupadd -r usergroup && useradd -m -r -g usergroup user
RUN chown -R user:usergroup /srv/frontend
USER user

RUN bower install

bower.json :

{
  "name": "code",
  "description": "",
  "main": "index.js",
  "authors": [
    "Mr. No One"
  ],
  "license": "ISC",
  "homepage": "",
  "ignore": [
    "**/.*",
    "node_modules",
    "bower_components",
    "test",
    "tests"
  ],
  "dependencies": {
    "angular": "^1.5.8"
  }
}

Gruntfile.json :

module.exports = function(grunt) {
    grunt.initConfig({});

    // tasks
    grunt.registerTask('default', []);
};

package.json :

{
  "name": "code",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "grunt": "^1.0.1"
  }
}

$ docker-compose up
... installing all dependencies ...
安装后，尝试运行 grunt 失败我在 docker-compose.yml 中指定的命令出现此错误的文件:

frontend_1  | grunt-cli: The grunt command line interface (v1.2.0)
frontend_1  | 
frontend_1  | Fatal error: Unable to find local grunt.
frontend_1  | 
frontend_1  | If you're seeing this message, grunt hasn't been installed locally to
frontend_1  | your project. For more information about installing and configuring grunt,

package.json实际上确实包括 grunt作为依赖项，它应该在 RUN npm install 之后安装.

做一个 docker exec -it <nameofyourcontainer> bash并查看 node_modules如果 grunt 安装在本地。

你设置了吗NODE_ENV至 production某处？
这会导致 npm不安装 devDepedencies .
