我正在Google Cloud上部署我的代码。测试时一切正常，但是当我跑步时：
gcloud app deploy
显示错误。基本上，我需要安装Node.js画布，这需要我已经在我的应用程序上安装的一些依赖项，但它仍然返回错误。以下是日志：

问题记录在案here。我要粘贴answer given：
显然我们缺少cairo模块 画布包需要（https://www.cairographics.org/），因此 安装失败。我们正在研究如何包含该模块 在基本图像中，我找到了canvas预制包 （https://www.npmjs.com/package/canvas-prebuilt）没有 安装问题。这对你有用吗？
在我的情况下它已经有效，所以我认为它是有效的。希望它也适合你。
