執行離子Cordova模擬android時出錯

Question

我創建了一個新的離子應用程序

ionic start test blank

在不進行任何更改的情況下，我嘗試運行Android Emulador

ionic cordova emulate android

控制台輸出

ort 35729 --r 35729 --iscordovaserve --externalIpRequired --nobrowser

有什么想法嗎？ 另一個離子應用程序也會發生相同的錯誤（這個新的空白應用程序是一個測試，用於檢查問題不是由我自己引起的）。 運行ionic cordova run android時發生相同的錯誤

• 離子性3.1.2
• 科爾多瓦7.0.1
• npm 3.10.9

更新：添加了ionic info輸出

global packages:

    @ionic/cli-utils : 1.1.2
    Cordova CLI      : 7.0.1
    Ionic CLI        : 3.1.2

local packages:

    @ionic/app-scripts              : 1.3.7
    @ionic/cli-plugin-cordova       : 1.1.2
    @ionic/cli-plugin-ionic-angular : 1.1.2
    Ionic Framework                 : ionic-angular 3.2.1

System:

    Node       : v7.1.0
    OS         : Windows 8.1
    Xcode      : not installed
    ios-deploy : not installed
    ios-sim    : not installed

ionic info警告我有一些更新，這些更新最終以新配置顯示：

global packages:

    @ionic/cli-utils : 1.3.0
    Cordova CLI      : 7.0.1
    Ionic CLI        : 3.3.0

local packages:

    @ionic/app-scripts              : 1.3.7
    @ionic/cli-plugin-cordova       : 1.3.0
    @ionic/cli-plugin-ionic-angular : 1.3.0
    Cordova Platforms               : android 6.2.3
    Ionic Framework                 : ionic-angular 3.2.1

System:

    Node       : v7.1.0
    OS         : Windows 8.1
    Xcode      : not installed
    ios-deploy : not installed
    ios-sim    : not installed

更新后錯誤仍然存​​在。

試圖ionic cordova run android --livereload但結果是相同的。

Answer 1

這應該工作：

離子科爾多瓦運行android --livereload
