我正在尝试在 Vue.js 中动态导入异步组件。

<template>
  <MyAsync></MyAsync>
</template>

<script>
import { defineAsyncComponent } from 'vue';

const component = 'lorem-ipsum-4';

export default {
  name: 'Article',
  components: {
    MyAsync: defineAsyncComponent(() => import(`@/articles/${component}.vue`)),
  },
};
</script>

但是，这不起作用并产生以下错误。

Failed to compile.

./src/views/Article.vue
Module build failed (from ./node_modules/eslint-loader/index.js):

然而静态导入工作得很好：

<template>
  <MyAsync></MyAsync>
</template>

<script>
import { defineAsyncComponent } from 'vue';

export default {
  name: 'Article',
  components: {
    MyAsync: defineAsyncComponent(() => import('@/articles/lorem-ipsum-4.vue')),
  },
};
</script>

这是一个使用 Vue CLI 创建的 Vue.js v3 项目。

可以在github上找到一个（非常少的）示例

有没有办法使动态导入工作？

export default {
  name: 'Article',
  components: {
    MyAsync: defineAsyncComponent(() => import('@/articles/'+ component +'.vue')),
  },
};

但是，我不认为这很好。

经过一些调试，我发现这是一个eslint 问题 template-curly-spacing，为了解决它，我将文件添加.eslintrc到项目根目录，内容如下：

{
    "plugins": [
        "vue"
      ],
    "rules" : {
        "template-curly-spacing": ["error", "never"]
      }
}

@在由以下组成的路径上替换./

export default {
  name: 'Article',
  components: {
    MyAsync: defineAsyncComponent(() => import(`./articles/${component}.vue`)),
  },
};

它对我有用
