To enable extensions, verify that they are enabled in those .ini files:
- /etc/php/5.6/cli/php.ini
- /etc/php/5.6/cli/conf.d/10-opcache.ini
- /etc/php/5.6/cli/conf.d/10-pdo.ini

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

我读过文章其中之一Ubuntu 16.04 默认自带 PHP7,但我们仍然可以使用 PHP5。但是我尝试了 PHP7 和 PHP5,仍然出现相同的错误!有什么想法吗?谢谢
答案1
如何在 Ubuntu 16.04 中安装 Laravel
更新:Laravel 5.4
由于对这个问题非常感兴趣,我决定更新它并创建一个小型 bash 脚本来安装使用 Laravel 所需的一切(这个是使用 NGINX 的)
https://github.com/emilas44/laravel-5.4-on-Ubuntu/blob/master/script.sh
您可以简单地复制并根据需要编辑它...也许您已经安装了一些脚本内的组件,如果是这样,您可以自由删除不需要的部分。
Laravel 5.2 如下:
安装基本内容(可选)
sudo apt-get install git
sudo apt-get install zip
灯
sudo apt-get install tasksel
sudo tasksel install lamp-server
卷曲
sudo apt-get install curl php-curl php-mcrypt php-mbstring php-gettext
启用模组
sudo phpenmod mcrypt
sudo phpenmod mbstring
sudo a2enmod rewrite
sudo systemctl restart apache2
作曲家
curl -sS https://getcomposer.org/installer | php
sudo mv composer.phar /usr/local/bin/composer
安装 phpmyadmin
sudo apt-get install phpmyadmin
稍后可通过 localhost/phpmyadmin 访问
创建 Laravel 项目
cd /var/www/html/
sudo composer create-project laravel/laravel work --prefer-dist
sudo chmod -R 777 work (do not set 777 on "live" server!)
创建虚拟主机 work.com
sudo gedit /etc/apache2/sites-available/work.com.conf
并将其粘贴到该文档中
#/etc/apache2/sites-available/work.com.conf contains following lines
<VirtualHost *:80>
ServerName work.com
DocumentRoot /var/www/html/work/public
<Directory /var/www/html/work/public>
AllowOverride All
Require all granted
</Directory>
</VirtualHost>
启用该站点
sudo a2ensite work.com
service apache2 reload
修复 hosts 文件,以便您可以通过 Web 浏览器访问它
sudo gedit /etc/hosts //space between gedit and destination!
#/etc/hosts contents following lines
127.0.0.1 work.com
或者使用此命令
sudo -- sh -c "echo '\n127.0.0.1 \twork.com'>> /etc/hosts"
就这样 laravel 就安装完成了!

答案2
我已经将 php 5.6.11 升级到 5.6.21。
因此,就我而言,我必须运行:
sudo apt-get install php5.6-mbstring
PS:我如何从 5.6.11 升级到 5.6.21 如下:
sudo LC_ALL=C.UTF-8 add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install php5.6
升级原因:zend_mm_heap 已损坏在作曲家更新期间。
答案3
这些是我在全新升级后在 Ubuntu Server 16.04 上安装 Laravel 5 的步骤
首先我必须彻底删除所有 PHP,正如 Mohammad Barhoush 所说:
sudo apt-get -y purge php.*
然后我使用以下命令重新安装了 PHP:
sudo apt install php libapache2-mod-php
sudo apt install php-cli
sudo apt install php-mysql
重新安装 PHP ver.7.0 后,我安装了 Mohhammad 推荐的附加相关软件包:
sudo apt-get install curl php-curl php-mcrypt php-mbstring php-gettext php-gd
并启用了模组
sudo phpenmod mcrypt
sudo phpenmod mbstring
最后,毕竟这个作曲家仍然很痛苦,抱怨它没有 zip 扩展名,所以
composer update
我安装了以下内容:sudo apt-get install php7.0-zip
此后它运行良好,没有任何错误!
这些是我从之前的 Ubuntu Server LTS 版本运行 laravel 5 所需的步骤。希望这对您有所帮助!谨致问候 :)

答案4
oerdnj 的解决方案有效,安装后你应该在运行之前mbstring
启用它。在我的例子中,laravel 需要 ext-mbstring 和 ext-dom:php.ini
composer install
apt-get install php-dom
