mpvue項目使用第三方UI框架vant weapp

我們搜到的教程都是說從vant-weapp的git倉庫中下載源碼，拷貝dist目錄到我們創建的mpvue項目文件的static或者dist或者…文件夾中，我覺得都可以吧，只是涉及你引用組件時的路徑怎麼寫。

這裏把vant-weapp的dist目錄重命名爲vant-weapp放在項目根目錄的static文件夾下：

在src文件夾下，即我們寫vue代碼的位置，正在編寫的頁面中添加main.json文件（vue代碼編譯成小程序代碼時會直接使用這個文件）:

{
  "usingComponents": {
    "van-button": "/static/vant-weapp/button/index"        
    //這個路徑是指根目錄下static文件中...
  }
}

ps: 我在app.json中引入, 即可全局使用

  },
  "sitemapLocation": "sitemap.json"
}

然後就可以運行了：cmd->

npm run dev
 

接着打開微信開發者工具，會發現報錯：

打開微信開發者工具的“詳情”右側欄，有一個ES6轉ES5：

把這個“ES6轉ES5”的選項勾上就不會報錯了…出現vant-weapp的樣式。
