=== Composer - как обновить 1.x до 2.x версии ===


Алгоритм обновления composer 1.x --> 2.x:

 # php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
 # php -r "copy('https://composer.github.io/installer.sig', 'composer-setup.sig');"
 # php -r "if (hash_file('sha384', 'composer-setup.php') === trim(file_get_contents('composer-setup.sig'))) { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
 # php composer-setup.php --install-dir=/usr/local/bin --filename=composer
 # php composer-setup.php --install-dir=/usr/bin --filename=composer

Удалить установочный файл:
 # php -r "unlink('composer-setup.php');"


Проверка:

 # which composer
 /usr/local/bin/composer
 # composer -V
