php - 为什么我无法在 ubuntu 16.04 上安装 PHP

Question

我一直在尝试在 ubuntu 16.04 上安装 laravel 3 天。我正在关注 laravel 安装过程的热门搜索链接。但是我没有执行我尝试过的每一个过程。现在我在我的 ubuntu 上安装 PHP 时遇到了不同的问题。我曾经安装过 maria db，但没有成功。 但它可能破坏了一些东西，导致我无法安装 PHP。我面临的问题:

Reading package lists... Done 
Building dependency tree       
Reading state information... Done
php is already the newest version (1:7.2+62+ubuntu16.04.1+deb.sury.org+3).
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
mysql-server : Depends: mysql-server-5.7 but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

当我尝试 php -v 时，它给了我这个错误

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20170718/mcrypt.so' (tried: /usr/lib/php/20170718/mcrypt.so (/usr/lib/php/20170718/mcrypt.so: cannot open shared object file: No such file or directory), /usr/lib/php/20170718//usr/lib/php/20170718/mcrypt.so.so (/usr/lib/php/20170718//usr/lib/php/20170718/mcrypt.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

我对 ubuntu 和 laravel 完全陌生。如果有人指导我如何在 ubuntu 16.04 上安装 laravel，我将非常感激。 谢谢。

• 安装 git apt-get install git-core

• git clone https://github.com/thamaraiselvam/LEMP-Stack-Installer.git

• cd quick-lemp-install 或 cd LEMP-Stack-Installer

• chmod +x lemp.sh 此命令使 bash 脚本可执行
• ./lemp.sh 就是这样:)

PHP version - v7.0

Mysql version - Latest Stable

Note: Default mysql password is root. you can change it before running in the following lines before running the script

sudo debconf-set-selections <<< 'mysql-server mysql-server/root_password password YOUR_PASSWORD'

sudo debconf-set-selections <<< 'mysql-server mysql-server/root_password_again password YOUR_PASSWORD'

现在安装 Laravel

• 转到 cd/var/www/html/
• sudo apt-get install php-common php-mbstring php-xml php-zip
• composer create-project --prefer-dist laravel/laravel blog "5.5.*"
