Php 错误消息：`composer_install`had stderr output

我正在将一个Laravel应用程序部署到Google App Engine标准环境中，但由于依赖关系问题，我在执行

gcloud App deploy

时遇到了一个PHP composer错误

我已经遵循了Google教程（）中的所有说明，但他们没有任何故障排除部分来解释这一点

这是我在

gcloud app deploy

之后在终端上遇到的错误：

Updating service [default]...failed.
ERROR: (gcloud.app.deploy) Error Response: [9] Cloud build 245bdb05-2dfa-4fe6-bdca-5e3e99221de1 status: FAILURE.
Error ID: 990D4641.
Error type: InternalError.
Error message: `composer_install` had stderr output:
Loading composer repositories with package information
Installing dependencies from lock file
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for ext-protobuf 3.7.0 -> satisfiable by ext-protobuf[3.7.0].
    - google/gax 1.0.0 conflicts with ext-protobuf[3.7.0].
    - Installation request for google/gax 1.0.0 -> satisfiable by google/gax[1.0.0].

  To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

error: `composer_install` returned code: 2.

这是我的app.yaml：

env_variables:
    ## Put production environment variables here.
    APP_KEY: [my_app_key]
    APP_STORAGE: /tmp
    VIEW_COMPILED_PATH: /tmp
    CACHE_DRIVER: database
    SESSION_DRIVER: database
    ## Set these environment variables according to your CloudSQL configuration.
    DB_DATABASE: [my_db]
    DB_USERNAME: root
    DB_PASSWORD: [my_super_secure_password]
    DB_SOCKET: "/cloudsql/test-project]:us-east1:test-db"
    LOG_CHANNEL: stackdriver

我需要能够在Google App Engine标准环境中部署应用程序而不出现此PHP composer错误。

我建议使用PECL安装并启用缺少的包

根据我分享的内容，您是如何得知grpc扩展丢失的？您的错误日志中说明了ext protobuf。搜索ext protobuf google cloud php时，我认为它找到了我提供的信息。
