自作した'nuxt_autolink'という.vueコンポーネントモジュールを、npm publishして公開したのですが、nuxt.jsのプロジェクトで、node_moduleからインストールして以下のように、使用したところ、

import NuxtAutolink from 'nuxt_autolink';
export default {  
    components: {
      NuxtAutolink,
    },
  };

nuxt.jsを、'npm run dev'で動かそうとすると、

以下のエラーが出ました。

39:18-30 "export 'default' (imported as 'NuxtAutolink') was not found in 'nuxt_autolink'

誰かわかるかたいらっしゃいますか??以下にそれぞれのファイルを載せておきます。全てのファイルを見たい方は、githubの方を見ていただければ、ご覧になれます。
