在使用 capistrano 部署的 symfony 项目的暂存中缺少 env 变量，但在哪里设置它？

如何解决在使用 capistrano 部署的 symfony 项目的暂存中缺少 env 变量，但在哪里设置它？

我尝试使用 capistrano 创建我的 staging 环境。但是我遇到了缺少环境变量的错误..

tail -f api-staging/current/var/logs/prod-{current_date}.log

PHP.CRITICAL: Uncaught Exception: Environment variable not found: "{project}__DATABASE_NAME_STAGING". {"exception":"[object] (Symfony\\Component\\DependencyInjection\\Exception\\EnvNotFoundException(code: 0): Environment variable not found: \"{project}__DATABASE_NAME_STAGING\". at /var/www/{project}/api-staging/shared/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/Container.PHP:445

我将在 default_env 文件中发送我的 staging.rb。

...
set :stage,"staging"
set :symfony_env,"staging"

set :branch,"staging"
set :deploy_to,'/var/www/{project}/api-staging'
set :controllers_to_clear,[]
set :composer_install_flags,'--prefer-dist --no-interaction --optimize-autoloader'

set :default_env,{ 
    ...
    '{project}__DATABASE_NAME_STAGING' => '{project}-staging',...
    'SYMFONY_ENV' => 'staging'
}
...

parameters_staging.yml.dist：

parameters:
...    
   database_name: '%env({project}__DATABASE_NAME_STAGING)%'
...

我在 .env、/api-staging、/api-staging/current 中有一个 /api-staging/shared 文件。 该变量可通过 printenv 命令查看。

还有一个 .env.dist 文件在

app_staging.PHP：

require __DIR__.'/../vendor/autoload.PHP';
Debug::enable();

if (file_exists(__DIR__ . '/../.env')) {
    $dotenv = new Dotenv();
    $dotenv->load(__DIR__ . '/../.env');
}

$kernel = new AppKernel('staging',false);

$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request,$response);

capistrano 部署脚本：
