PHP LAMP configuration

OS: Ubuntu 17.10
I installed the LAMP and Laravel stack, and when I tried composer installin my Laravel application, I got the following errors.

  - Installation request for phar-io/manifest 1.0.1 -> satisfiable by phar-io/manifest[1.0.1].
    - phar-io/manifest 1.0.1 requires ext-dom * -> the requested PHP extension dom is missing from your system.

    - phpunit/phpunit 6.4.3 requires ext-dom * -> the requested PHP extension dom is missing from your system.

  To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php/7.1/cli/php.ini
    - /etc/php/7.1/cli/conf.d/10-opcache.ini
    - /etc/php/7.1/cli/conf.d/10-pdo.ini
    - /etc/php/7.1/cli/conf.d/20-calendar.ini
    - /etc/php/7.1/cli/conf.d/20-ctype.ini
    - /etc/php/7.1/cli/conf.d/20-exif.ini
    - /etc/php/7.1/cli/conf.d/20-fileinfo.ini
    - /etc/php/7.1/cli/conf.d/20-ftp.ini
    - /etc/php/7.1/cli/conf.d/20-gettext.ini
    - /etc/php/7.1/cli/conf.d/20-iconv.ini
    - /etc/php/7.1/cli/conf.d/20-json.ini
    - /etc/php/7.1/cli/conf.d/20-mbstring.ini
    - /etc/php/7.1/cli/conf.d/20-pdo.ini
    - /etc/php/7.1/cli/conf.d/20-phar.ini
    - /etc/php/7.1/cli/conf.d/20-posix.ini
    - /etc/php/7.1/cli/conf.d/20-readline.ini
    - /etc/php/7.1/cli/conf.d/20-shmop.ini
    - /etc/php/7.1/cli/conf.d/20-sockets.ini
    - /etc/php/7.1/cli/conf.d/20-sysvmsg.ini
    - /etc/php/7.1/cli/conf.d/20-sysvsem.ini
    - /etc/php/7.1/cli/conf.d/20-sysvshm.ini
    - /etc/php/7.1/cli/conf.d/20-tokenizer.ini
  You can also run 'php --ini' inside terminal to see which files are used by PHP in CLI mode.

I double-checked the files, all extensions are included, and they are in the folder /usr/lib/php/20160303.

Sometimes the problem is php-xml extension.

Try:

sudo apt-get install php-xml
+48
source

If the problem persists, try

sudo apt-get install -y php7.1 php7.1-xml php7.1-mysql php7.1-curl php7.1-mbstring

+7
source

:

sudo apt-get install php-mbstring
sudo apt-get install php-xml
+3

, dom. :

 sudo apt install php7.1-dom

If the log is missing only one extension, the above command works. If there are no other extensions, you can add these extensions on the same line as shown below:

sudo apt install php7.1-dom php7.1-ext-mbstring

This is it. Now you will have no problems installing the composer. Enter composer install
