json - 在 Linux 上使用 gaction 更新 Google Home/Assistant 包时 Golang runtime panic？

Question

我正在尝试使用本教程中的说明在 Linux 14.04 LTS 机器(而非 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

我的应用成功部署到 Google Cloud。但是，当我到达您使用模拟器测试您的应用程序的部分时，以下gactions 命令失败并显示消息“没有预览/模拟的帮助主题”

$ 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 Actions 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 panic 崩溃并出现以下堆栈跟踪:

    panic: runtime error: invalid memory address or nil pointer dereference [recovered]
    panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x506df6]

下面是我的包文件 (action.json)，我使用 JSON 验证器对其进行了验证:

{
    "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"
        }
    }]
}

如何解决此问题并让我的 Google Home/智能助理应用正常运行？

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 .

这可能是我系统的错误版本吗？我正在运行 Ubuntu 14.04 LTS，64 位版本。

Answer 1

有一个新的 gactions 版本可用。试试 gactions selfupdate。

如果因为版本损坏而无法正常工作，请下载 old version并运行它。这个旧版本然后更新到 2.1.1，一切都恢复正常。
