  },
  "devDependencies": {
    "autoprefixer": "^7.1.2",
    "babel-core": "^6.25.0",
    "babel-eslint": "^6.0.4",
    "babel-loader": "^7.1.1",
    "babel-plugin-transform-runtime": "^6.23.0",
    "babel-preset-es2015": "^6.24.1",
    "babel-preset-stage-3": "^6.24.1",
    "chunk-manifest-webpack-plugin": "^1.1.0",
    "cors": "^2.8.3",
    "cross-env": "^5.0.1",
    "css-loader": "^0.28.4",
    "eslint": "^3.19.0",
    "eslint-config-standard": "^6.2.1",
    "eslint-plugin-html": "^2.0.0",
    "eslint-plugin-import": "^2.7.0",
    "eslint-plugin-promise": "^3.4.0",
    "eslint-plugin-standard": "^2.0.1",
    "extract-text-webpack-plugin": "^2.1.2",
    "file-loader": "^0.11.2",
    "friendly-errors-webpack-plugin": "^1.6.1",
    "happypack": "^4.0.0-beta.1",
    "html-webpack-plugin": "^2.29.0",
    "less": "^2.7.2",
    "less-loader": "^4.0.4",
    "opn-cli": "^3.1.0",
    "os": "^0.1.1",
    "postcss-loader": "^2.0.6",
    "rimraf": "^2.6.1",
    "style-loader": "^0.18.2",
    "url-loader": "^0.5.9",

    "vue-template-compiler": "^2.4.1",
    "webpack": "^3.3.0",
    "webpack-chunk-hash": "^0.4.0",
    "webpack-dev-server": "^2.5.1",
    "webpack-merge": "^4.1.0"
  },

代码如下：

<template>
  <Row :gutter="30" class="order-page">
    <Col :md="12">
      <sell-and-buy></sell-and-buy>
    </Col>
    <Col :md="12">
      <asks-and-dids></asks-and-dids>
    </Col>
  </Row>
</template>
<script>
import SellAndBuy from './SellAndBuy.vue';
import AsksAndDids from './AsksAndDids.vue';
export default {
  name: 'order',
  components: {
    sellAndBuy: SellAndBuy,
    asksAndDids: AsksAndDids
  }
}
</script>
<style lang="less">
</style>

在webpack-dev-server的开发环境下能正常启动，但热更新后刷新浏览器时有时会报以下错误：

但把自己的引入的组件去掉，刷新下浏览器又能重新运行了。

去掉自己引入的组件后代码如下：

<template>
  <Row :gutter="30" class="order-page">
    <Col :md="12">
    </Col>
    <Col :md="12">
    </Col>
  </Row>
</template>
<script>
import SellAndBuy from './SellAndBuy.vue';
import AsksAndDids from './AsksAndDids.vue';
export default {
  name: 'order',
  components: {
    sellAndBuy: SellAndBuy,
    asksAndDids: AsksAndDids
  }
}
</script>
<style lang="less">
</style>

Answer 1

components: {
    sellAndBuy: SellAndBuy,
    asksAndDids: AsksAndDids
  }

这里写的不对, 导致组件渲染失败

Answer 2

应该是webpack版本的问题
