异常:

RuntimeExceptionin EncryptionServiceProvider.php line 29:

No supported encrypter found. The cipher and / or key length are invalid.


php artisan key:generate

然后将 生成的 32位key. 放到 config/app.php 下面的 APP_KEY  ;  以及 .env 中的 APP_KEY

之后  php artisan serve  错误依旧~~~~~~~


问题已解决:

    原因是  未使用 sudo php artisan serve 导致无权限读取文件,无法获取APP_KEY
