     To enable extensions, verify that they are enabled in your .ini files: 
     - /etc/php/7.0/cli/php.ini 
     - /etc/php/7.0/cli/conf.d/10-opcache.ini 
     - /etc/php/7.0/cli/conf.d/10-pdo.ini 
     - /etc/php/7.0/cli/conf.d/20-calendar.ini 
     - /etc/php/7.0/cli/conf.d/20-ctype.ini

     - /etc/php/7.0/cli/conf.d/20-tokenizer.ini 
     - /etc/php/7.0/cli/conf.d/20-zip.ini 
     You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode. 
    Application ready! Build something amazing.

也越來越錯誤而執行即成命令

[email protected]:~/Documents/lartest/demo$ php artisan serve 
PHP Warning: require(/home/ninja/Documents/lartest/demo/bootstrap/../vendor/autoload.php): failed to open stream: No such file or directory in /home/ninja/Documents/lartest/demo/bootstrap/autoload.php on line 17

假設你已經安裝了php7.0-CLI成功。

現在，在你的終端運行以下命令：

sudo apt-get install php7.0-mbstring 
sudo apt-get install php7.0-xml

然後嘗試重新安裝Laravel。

讓我知道你是否仍然面臨任何問題。
