nuxt start要求存在node_modules才能运行

我有一个nuxt-community/starter-template最少添加的项目。我package.json看起来像这样

{
  // ...
  "scripts": {
    "dev": "nuxt",
    "build": "nuxt build",
    "docker-image": "nuxt build && docker build -t unijobs-www-temp .",
    "start": "nuxt start",
    "generate": "NODE_ENV=production nuxt generate",
    "lint": "eslint --ext .js,.vue --ignore-path .gitignore .",
    "precommit": "npm run lint"
  },
  "dependencies": {
    "@fortawesome/fontawesome": "^1.1.8",
    "@fortawesome/fontawesome-free-brands": "^5.0.13",
    "@fortawesome/fontawesome-free-regular": "^5.0.13",
    "@fortawesome/fontawesome-free-solid": "^5.0.13",
    "@fortawesome/vue-fontawesome": "0.0.22",
    "nuxt": "^1.0.0",
    "nuxt-fontawesome": "^0.2.0",
    "node-sass": "^4.9.0",
    "sass-loader": "^7.0.2"
  },
  "devDependencies": {
    "babel-eslint": "^8.2.1",
    "eslint": "^4.15.0",
    "eslint-friendly-formatter": "^3.0.0",
    "eslint-loader": "^1.7.1",
    "eslint-plugin-vue": "^4.0.0"
  }
}

本地开发看起来不错，在本地build也start可以正常工作。但是，当我构建Docker映像时，一切都朝南。 请注意，这不是Docker的问题，如果我在自己的计算机上的新目录中运行等效步骤，也是如此。

FROM node:stretch

ENV NODE_ENV=production
ENV HOST=0.0.0.0
EXPOSE 3000

RUN npm -g i nuxt
RUN mkdir -p /app
ADD .nuxt /app/.nuxt
ADD static /app/static
WORKDIR /app

CMD ["nuxt", "start"]

这是我在日志中找到的：

然而，这一切，只要我插上消失node_modules的，旁边.nuxt和static目录。似乎某些模块未捆绑在一起。我的nuxt.config.js档案就像

module.exports = {
  head: {
    // Skipping noise...
  },
  modules: [
    [ 'nuxt-fontawesome', {
      component: 'fa',
      imports: [
        { set: '@fortawesome/fontawesome-free-brands' },
      ]
    }],
  ],
  loading: { color: '#3B8070' },
  build: {
    extend (config, { isDev, isClient }) {
      if (isDev && isClient) {
        config.module.rules.push({
          enforce: 'pre',
          test: /\.(js|vue)$/,
          loader: 'eslint-loader',
          exclude: /(node_modules)/
        })

// *** NOTE: In practice, I'm only using FA brands here, not the others ***

        config.resolve.alias['@fortawesome/fontawesome-free-brands$'] = '@fortawesome/fontawesome-free-brands/shakable.es.js'  
      }
    }
  }
}

难道我做错了什么？
