Почему Composer не обновляется?

14

Я использую Ubuntu 16.04 LTS amd64. Я установил LAMP (php5.6, apache2, mysql) и Composer. Я скачал свой проект Laravel с GitHub. Я хотел бы обновить Composer для запуска локального сервера php artisan serve. Но когда я хотел бы запустить localhost, терминал говорит:

heartprogrammer@heartprogrammer-desktop:/var/www/kstu$ php artisan serve
PHP Warning:  require(/var/www/kstu/bootstrap/../vendor/autoload.php): failed to open stream: No such file or directory in /var/www/kstu/bootstrap/autoload.php on line 17
PHP Fatal error:  require(): Failed opening required '/var/www/kstu/bootstrap/../vendor/autoload.php' (include_path='.:/usr/share/php') in /var/www/kstu/bootstrap/autoload.php on line 17

Я пытался обновить Composer, но он говорит:

heartprogrammer@heartprogrammer-desktop:/var/www/kstu$ composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Вам необходимо установить расширение php dom.

sudo apt-get install php-xml

Но так как вы все еще используете php5.6 ...

sudo apt-get install php5.6-xml

... сделаю трюк.

Можно установить необходимые пакеты 1 на 1. Но для облегчения жизни попробуйте

sudo apt-get install php5.6-*

это установит все, что связано с php5.6

Вам нужно установить php5.6-xml sudo apt-get install -y php5.6-xmlи composer update. Скорее всего, вам не хватает mbstring тоже. Если вы получили ошибку, установите этот пакет также с:sudo apt-get install php-mbstring
