我已经试着在ubuntu16.04上安装laravel三天了。我下面的拉威尔安装过程的顶部搜索链接。但我没能执行我尝试过的每一个过程。现在，在我的ubuntu上安装php时，我面临着一个不同的问题。我曾经安装过mariadb，但没有成功。但它可能破坏了某些东西，导致我无法安装php。我面临的问题是：
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).当我尝试的时候 php -v 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

sudo dpkg -l | grep mysql通过执行以下命令删除上面显示的包sudo apt-get --purge autoremove <packages from the step 1>删除/var/lib/mysql尝试安装mysql再一次。它应该能解决你的问题mrphzbgm2#
安装git
apt-get install git-coregit clone https://github.com/thamaraiselvam/LEMP-Stack-Installer.gitcd quick-lemp-install或cd lemp堆栈安装程序chmod +x lemp.sh此命令使bash脚本可执行./lemp.sh就这样：）php版本-v7.0
mysql版本-最新稳定
注意：默认mysql密码是root。在运行脚本之前，可以在以下行中更改它
sudo debconf set selections<<<'mysql server mysql server/root\u password密码您的\u密码'
sudo debconf set selections<<<'mysql server mysql server/root\u password\u再次输入您的密码'
现在安装laravel
