Php google/cloud firestore v1.17.0需要ext grpc

使用免费试用谷歌云平台并遵循指南：

在Cloud Shell终端上当我运行命令“php index.php”而不部署它时，一切正常。使用以下composer.json

{
  "require": {
    "php": "7.2.*",
    "silex/silex": "^2.3",
    "google/cloud-firestore": "^1.17",
    "grpc/grpc": "^v1.27.0",
    "google/protobuf": "^v3.3.0"
  },
  "require-dev": {
    "symfony/browser-kit": "^4.4",
    "symfony/http-kernel": "^4.4"
  }
}

但如果我部署它是为了生成一个web，如中的命令所示：

gcloud应用程序部署

它会得到以下错误：

第1步：运行composer。。。
步骤#1：使用包信息加载composer存储库
步骤#1：从锁文件安装依赖项

当然，我在/etc/php/7.2/cli/php.ini中添加了行扩展名=grpc.so。我执行命令php--ini以查找所有文件。

我知道这个问题似乎在重复，但这个问题还没有解决。

谷歌云SDK的每个版本都有改进。请运行命令：“gcloud组件更新”，然后再次尝试部署应用程序。
