我正在使用Laravel构建一个项目。在localhost上运行正常，但是当我将其上载到服务器（服务器已安装comodo ssl）时，出现以下错误：

RuntimeException in EncryptionServiceProvider.php line 29:
No supported encrypter found. The cipher and / or key length are invalid
in EncryptionServiceProvider.php line 29

at Kernel->handle(object(Request)) in index.php line 54

谁能帮助解决此错误？

回答：

服务器上是否已安装所有必需的扩展程序？

  • PHP> = 5.5.9

  • OpenSSL PHP扩展

  • PDO PHP扩展

  • Mbstring PHP扩展

  • Tokenizer PHP扩展

可能是您缺少OpenSSL扩展名。另外，您是否在.env文件中设置了密钥？

尝试运行：

php artisan key:generate

答：'cipher' => ''没有设置。
