由于缺少PHP扩展，无法在Synology NAS（DSM 6）上安装Laravel

Question

我尝试使用DSM 6在我的Synology NAS上的Web Station上安装Laravel。安装作曲家后，我运行命令composer create-project laravel/laravel web-project，但我得到的只是这个错误。

  To enable extensions, verify that they are enabled in those .ini files:
    - /etc/php/php.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

还检查了我的Web Station配置，发现遗留的tokenizer扩展名没有，但我看不到安装它的选项。

所以，我的问题是：如何在Synology NAS上将tokenizer扩展添加到PHP？ PHP版本是5.6。

由于

Answer 1

你必须使用php56而不是php命令。 例子：php56 composer.phar create-project laravel / laravel theproject“5.2。*”

Answer 2

运行composer self-update然后尝试在新文件夹中创建项目。

并且失败，您可以将laravel版本更改为下面的版本，例如composer create-project laravel/laravel web-project "5.2.*"
