Question

我有点像 laravel 和 mint 的新手。我只是无法把东西拿出来 - 发生了什么事。实际上，我需要一些像猴子一样的答案。所以无论我会接受任何问题，非常感谢您的帮助。

  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Answer 1

您缺少 PHP 中的 mbstring 扩展。我不确定 Mint 是否使用 apt 或其他一些包管理器，购买试试:

sudo apt-get install php7.0-mbstring

和

phpenmod mbstring

您可能需要尝试使用这些命令来匹配您的 PHP 版本，但这应该能让您入门。
