Question

我正在使用docker-compose开发一个多模块docker nodejs应用程序。模块所需的natural节点包存在问题。它似乎无法执行它。我尝试使用RUN命令在运行中重建它，但没有任何改变。这是尝试运行docker-compose up时的日志：

web_1         | /app/web-server/node_modules/natural/lib/natural/classifiers/classifier.js:32
web_1         |     if (e.code !== 'MODULE_NOT_FOUND') throw e;
web_1         |                                        ^
web_1         |
web_1         | Error: Error loading shared library /app/web-server/node_modules/webworker-threads/build/Release/WebWorkerThreads.node: Exec format error

web_1         |     at require (internal/module.js:20:19)

这是package.json：

{
  "name": "realaffinities",
  "version": "1.0.0",
  "description": "",
  "main": "server/Server.js",
  "keywords": [],
  "author": "",
  "license": "GPL-3.0",
  "dependencies": {
    "async": "^2.5.0",
    "big-integer": "^1.6.23",
    "body-parser": "1.9.0",
    "express": "^4.15.3",
    "express-validator": "^3.2.1",
    "knex": "^0.13.0",
    "mysql": "^2.14.1",
    "natural": "^0.5.4",
    "twit": "^2.2.9",
    "url-exists": "^1.0.3",
    "nodemon": "^1.11.0"
  },
  "devDependencies": {
    "grunt": "^1.0.1",
    "grunt-express-server": "^0.5.3",
    "mocha": "^3.4.2",
    "supertest": "^3.0.0",
    "bcrypt": "1.0.2"
  },
  "scripts": {
    "test": "mocha web-server/test",
    "start": "node server/Server.js"
  }
}

我的dockerfile：

FROM node:6.11-alpine

EXPOSE 3000
ENV NODE_ENV development
RUN mkdir /app
WORKDIR /app

# add package.json and run npm install before adding the rest of the files
# this way, you only run npm install when package.json changes
ADD /web-server/package.json /app/package.json

RUN apk add --no-cache make gcc g++ python

RUN npm install -g mocha
RUN npm install

我不知道这是一个特定节点包的问题还是我的知识缺乏。如果我在没有docker的Mac上本地运行相同的应用程序，它就不会遇到这个问题。

有人在this问题中报告了同样的问题，他的案例与您的案例相似。正如评论中所讨论的，这对您有用，所以我也将其作为答案发布：

听起来它正在尝试加载一个不是原生的扩展程序为linux编译（在容器中） - 也许你以前在OS X上安装了扩展，并且它正在尝试加载该二进制文件。如果您的意思是这是一个节点应用程序，请尝试删除node_modules并运行 npm再次安装
