webman 使用phar打包后，如何读取.env文件？

根据webman文档中的打包，我已经把项目打包到build/program.phar
但是运行这个打包后，发现并不是读取.env配置的。 我试着把.env文件放到program.phar同级目录下，依旧不行。
下面是我的.env配置：

NAME=program
DEBUG=true
LISTEN=http://192.168.10.10:8787

这是config/app.php配置

return [
    'debug' => env('DEBUG',true),
    'default_timezone' => 'Asia/Shanghai',
];

这是config/server.php配置

return [
    'listen'               => env('LISTEN','http://0.0.0.0:8787'),
    'transport'            => env('TRANSPORT','tcp'),
    'context'              => [],
    'name'                 => env('NAME',''),
    'count'                => env('HTTP_PROCESS_COUNT',cpu_count() * 2),
    'user'                 => 'root',
    'group'                => 'root',
    'reusePort'            => false,
    'pid_file'             => runtime_path() . '/webman.pid',
    'status_file'          => runtime_path() . '/webman.status',
    'stdout_file'          => runtime_path() . '/logs/stdout.log',
    'log_file'             => runtime_path() . '/logs/workerman.log',
    'max_package_size'     => 10*1024*1024
];

这是config/plugin/webman/console/app.php

return [
    'enable'            => true,

    'phar_file_output_dir'    => BASE_PATH . DIRECTORY_SEPARATOR . 'build',

    'phar_filename'     => 'program.phar',

    'signature_algorithm'=> Phar::SHA256, //set the signature algorithm for a phar and apply it. The signature algorithm must be one of Phar::MD5, Phar::SHA1, Phar::SHA256, Phar::SHA512, or Phar::OPENSSL.

    'private_key_file'  => '', // The file path for certificate or OpenSSL private key file.

    'exclude_pattern'   => '#^(?!.*(config/plugin/webman/console/app.php|webman/console/src/Commands/(PharPackCommand.php|ReloadCommand.php)|LICENSE|composer.json|.github|.idea|doc|docs|.git|.setting|runtime|test|test_old|tests|Tests|vendor-bin|.md))(.*)$#',

    'exclude_files'     => [
        '.env', 'LICENSE', 'composer.json', 'composer.lock','start.php'
    ]
];

以上配置执行php start.php start 都是正常读取.env配置的

打包后，只能读取到env()函数的默认值

感谢帮忙看一下
