【问题描述】：

最近除了 app.yaml 中的环境变量之外没有任何代码更改，应用引擎部署在云构建过程中失败，超出内存限制，我不明白我在哪里可以更改它，或者为什么它会成为问题.. . 我尝试设置“gcp-build”来覆盖composer install 命令，但在云构建过程中出现此错误：

Step #3 - "detector": ======== Output: google.php.composer-gcp-build@0.9.0 ========
Step #3 - "detector": unmarshalling composer.json: json: cannot unmarshal array into Go struct field     composerScriptsJSON.scripts.gcp-build of type string [id:070ec49f]
Step #3 - "detector": ======== Results ========

这是我的 composer.json：

}

另外，当我在云构建期间收到此警告时，是否有机会将 composer 更新到 v2：

Step #6 - "builder": Warning from https://repo.packagist.org: You are using an outdated version of Composer. Composer 2.0 is now available and you should upgrade. See https://getcomposer.org/2

这是构建失败的实际问题：

app.yaml 中使用的运行时是 php74，也尝试将其更改为 php72，同样的问题

【问题讨论】：

如果您的应用程序文件夹中没有 composer.lock 文件，请尝试运行命令composer install，如果 composer.lock 存在，请尝试运行composer update。然后，使用命令gcloud app deploy --no-cache 部署您的应用程序，以确保更新依赖项。
@john-michael-g 谢谢！它确实有帮助
我认为这样做可以解决您的问题

【解决方案1】：

由于您部署的应用程序已经有一个从 App Engine 部署生成的 composer.lock 文件，并且默认情况下，App Engine 会缓存获取的依赖项以减少构建时间。它将阻止您自动获取最新版本的依赖项，您将遇到错误：

您使用的是过时版本的 Composer

要解决此问题，请在本地运行命令 composer install 以将您的依赖项固定到其当前版本，如果 composer.lock存在，则拥有 composer.lock 和 composer update。然后使用命令 'gcloud beta app deploy --no-cache' 进行部署以安装依赖项的未缓存版本。
