Почему laravel не хочет запускать локальный хост localhost:8000?

Поставил фреймворк laravel на ОС Ubuntu 16.04. Решил значит запустить локальный хост командой php artisan serve

Так laravel выдает такую ошибку 
PHP Warning:  require(/var/www/laravel/bootstrap/../vendor/autoload.php): failed to open stream: No such file or directory in /var/www/laravel/bootstrap/autoload.php on line 17
PHP Fatal error:  require(): Failed opening required '/var/www/laravel/bootstrap/../vendor/autoload.php' (include_path='.:/usr/share/php') in /var/www/laravel/bootstrap/autoload.php on line 17


Читал то что надо установить composer командой composer install
Установил его, и после установки выдало это
Cannot create cache directory /home/heartprogrammer/.composer/cache/repo/https---packagist.org/, or directory is not writable. Proceeding without cache

  To enable extensions, verify that they are enabled in those .ini files:
    - /etc/php/5.6/cli/php.ini
    - /etc/php/5.6/cli/conf.d/10-opcache.ini
    - /etc/php/5.6/cli/conf.d/10-pdo.ini

    - /etc/php/5.6/cli/conf.d/20-calendar.ini
    - /etc/php/5.6/cli/conf.d/20-ctype.ini
    - /etc/php/5.6/cli/conf.d/20-dom.ini
    - /etc/php/5.6/cli/conf.d/20-exif.ini

    - /etc/php/5.6/cli/conf.d/20-xmlwriter.ini
    - /etc/php/5.6/cli/conf.d/20-xsl.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.


И так же не получается запустить локальный хост. С чем это связано?

directory is not writable

Это говорит о том что нужно разобраться с правами на папки
Попробуйте
sudo chmod -R 777 /home/heartprogrammer/.composer/

В файле php.ini нужно найти строчку
;extension=mbstring
и раскомментировать (убрать знак ";" перед)
