我正在尝试按照本教程中的说明在Linux 14.04 LTS盒子（不是Windows）上构建我的第一个Google Home应用：

https://medium.com/google-cloud/building-your-first-action-for-google-home-in-30-minutes-ec6c65b7bd32

我的应用程序到Google Cloud的部署成功。但是，当我到达使用模拟器测试应用程序的部分时，以下 gactions
命令失败，并显示消息“无帮助主题以供预览/模拟”

$ gactions preview --action_package action.json --invocation_name "three doors" --preview_mins 1234

No help topic for 'preview'

和：

$ gactions simulate

No help topic for 'simulate'

然后，我尝试在此处切换到模拟器的Google操作说明：

https://developers.google.com/actions/tools/simulator

该文档指示我使用以下命令上传我的Actions项目：

$ gactions update --action_package action.json --project three-doors-9898

但这会导致Golang恐慌崩溃，并带有以下堆栈跟踪：

    panic: runtime error: invalid memory address or nil pointer dereference [recovered]
    panic: runtime error: invalid memory address or nil pointer dereference

以下是我的程序包文件（ action.json ），我确实使用JSON验证程序进行了验证：

{
    "versionLabel": "1.0",
    "agentInfo": {
        "languageCode": "en-US",
        "projectId": "three-doors-9898",
        "voiceName": "male_1"
    },
    "actions": [{
        "description": "Launch intent",
        "initialTrigger": {
            "intent": "assistant.intent.action.MAIN"
        },
        "httpExecution": {
            "url": "https://us-central1-three-doors-9898.cloudfunctions.net/three_doors"
        }
    }]
}

如何解决此问题并使我的Google Home / Assistant应用正常运行？

更新 ：我使用的 gactions 版本来自这里：

我使用此页面上的 Linux / x86_64 链接来获取它：

https://developers.google.com/actions/tools/gactions-
cli 。

这可能是我的系统版本错误吗？我正在运行64位版本的Ubuntu 14.04 LTS。
