laravel找不到支持的加密器。密码和/或密钥长度无效

Question

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

谁能帮助解决此错误？

Answer 1

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。
