【问题描述】：

我的 API 中有上述错误。我正在使用 Laravel 版本 8，并将 API 部署在 Google Cloud App Engine 上。

我按照this tutorial的指示。我正在尝试将生成的文件存储在 /tmp 文件夹中并将其上传到 Google Cloud Storage。按照教程到Set up Stackdriver Logging and Error Reporting，但我得到了

There is no existing directory at ".../storage/logs" and it could not be created: Read-only file system

我对 DevOps 知识知之甚少，感谢您提供的任何帮助。

这是我的app.yaml 文件

runtime: php73

env_variables:
  ## Put production environment variables here.
  LOG_CHANNEL: stackdriver
  APP_KEY: my_app_key
  APP_STORAGE: /tmp
  VIEW_COMPILED_PATH: /tmp
  SESSION_DRIVER: cookie

在我的filesystems.php 文件中，我将符号链接设置为/tmp 文件夹

'links' => [
        public_path('storage') => storage_path('/tmp'),
],

这是我的 composer.json 文件

【问题讨论】：

好像和这个question类似
是的，@JohnMichaelGelilio 你是对的，但是，我在那里找不到解决方案。我已尝试更改 composer.json 文件中的权限。该教程引用了laravel version 5.4，我正在寻找使用更高版本部署它的人。我对云的了解很少。

【解决方案1】：

GAE 无法访问标准环境中的本地文件/存储，在这种情况下通常会给出 Read-only file system 错误。

由于您正在遵循适用于 GAE 标准的官方 Google 教程，请确认您的代码中的路径 $app->useStoragePath(env('APP_STORAGE', base_path() . '/storage'));（来自教程）实际上指向 google cloud env 上的路径，而不是您的本地文件结构。
