如何在Node.js上安裝socket.io和mysql

Question

我對Node.js還是個新手。

我正在嘗試設置一個基本站點（以便學習），以便從前端的Javascript調用Node.js並返回mysql查詢的數據。

我按照互聯網上的一些教程進行操作，並制作了這個packages.json文件

{
    "name": "Stock",
    "version": "0.0.1",
    "devDependencies": {
        "grunt": "~0.4.5",
        "grunt-contrib-watch": "^0.6.1",
        "grunt-execute": "^0.2.2",
        "socket.io":"lastest"
    }
}

然后在我的Linux上運行： npm install我了解它將安裝在packages.json中列出的所有依賴項。 但我收到此錯誤：

我猜想是socket.io的latest版本，不好嗎？ 如何運作？

我從這里獲得的部分代碼

Answer 1

您在socket.io版本中有一個錯字。 "socket.io":"lastest"應更改為"socket.io":"latest" 。

Answer 2

應該是“最新的”而不是“最新的”
