我使用以下步骤在gcloud上部署了Laravel应用：
php artisan key:generate --show
php artisan cache:clear
php artisan config:clear
php artisan view:clear
php artisan route:clear
gcloud beta app deploy --no-cache
我在composer.json中具有以下内容：
"post-install-cmd": [
"Illuminate\\Foundation\\ComposerScripts::postInstall",
"php artisan optimize",
"chmod -R 777 bootstrap\/cache",
"chmod -R 777 storage\/logs",
"php artisan cache:clear"
]
app.yaml内容如下：
runtime: php72
runtime_config:
document_root: public
env_variables:
# Put production environment variables here.
APP_LOG: errorlog
APP_KEY: base64:js8r1FFX55XhAcXVjU71plGXGTCt4YrauCqXFHjlsO4=
APP_STORAGE: /tmp
VIEW_COMPILED_PATH: /tmp
CACHE_DRIVER: cookie
SESSION_DRIVER: cookie
## Set these environment variables according to your CloudSQL configuration.
CLOUDSQL_USER: root
CLOUDSQL_PASSWORD: secret
CLOUD_SQL_DSN: "mysql:dbname=cbt-sql;unix_socket=/cloudsql/theta-byte-123456:asia-southeast1:cbt-sql"
但是，出现以下错误。我不确定自己在做什么错。
