Laravel 7 需要以下 php 个模块
- php-zip
- php-mysql
- php-mcrypt
- php-xml
- php-mbstring
使用以下代码在 fedora/centos/rhel 上安装它们。这将仅安装缺少的模块，
yum --enablerepo=remi,epel install php-zip php-mysql php-mcrypt php-xml php-mbstring
service httpd restart
for ubuntu/debian 检查当前安装的 php 版本并相应地安装模块。例如，如果安装了 php 7.2，请使用以下代码。
sudo apt install libapache2-mod-php7.2 php7.2-mcrypt php7.2-mbstring php7.2-xmlrpc php7.2-soap php7.2-gd php7.2-xml php7.2-cli php7.2-zip php7.2-mysql
sudo systemctl restart apache2.service
