Ionic 3 ionic serve命令自行终止

Question

我在ionic serve命令中遇到错误。我可以通过npm run ionic : serve为应用程序提供服务。我搜索了有关这方面的内容，还添加了ionic serve的输出--verbos.请帮助解决这个问题。

离子信息输出是这样的：

cli packages: (C:\Users\DELL\AppData\Roaming\npm\node_modules)

        @ionic/cli-utils  : 1.19.1
        ionic (Ionic CLI) : 3.19.1

    global packages:

        cordova (Cordova CLI) : 8.0.0

    local packages:

        @ionic/app-scripts : 3.1.8
        Cordova Platforms  : windows broken
        Ionic Framework    : ionic-angular 3.9.2

    System:

        Node : v8.4.0
        npm  : 5.3.0
        OS   : Windows 8.1

    Environment Variables:

        ANDROID_HOME : C:\Users\DELL\AppData\Local\Android\sdk;%ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools

ionic serve --详细输出如下：

Answer 1

看起来您的应用程序已在运行，但未在浏览器选项卡中打开。您可以强制ionic在特定浏览器中打开应用程序，如：-

ionic serve -w铬(用于铬)

ionic serve -w火狐(用于mozila)

也许这会有所帮助。

Answer 2

ionic serve -d它起作用了，它可以帮助你。

Answer 3

尝试下面的命令，

npm run ionic:serve -l

这与ionic serve -l的工作方式类似
