nuxt start 需要 node_modules 存在才能运行

Question

我有一个 nuxt-community/starter-template 项目，只添加了最少的内容。我的 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，本地 build 和 start 似乎工作正常。但是，当我构建 Docker 图像时，一切都变糟了。 请注意 这不是 Docker 的问题，如果我运行在我自己的机器上的新目录中执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内容：

2018-06-05T12:27:19.910Z nuxt:render Rendering url /

  code: 'MODULE_NOT_FOUND',
  statusCode: 500,
  name: 'NuxtServerError' }

但是，一旦我在 .nuxt 和 static 目录旁边插入 node_modules，这一切都消失了。似乎有些模块没有捆绑。我的 nuxt.config.js 文件就像

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'  
      }
    }
  }
}

我是不是做错了什么？

我发现 Nuxt 构建不会在 node_modules 中打包文件，所以如果你想将所有依赖项打包到 .nuxt 中，你应该使用 nuxt build --standalone。
