Failed to stat on composer.phar?

Question

Composer

Installed according to different manuals composer. But still, after a successful installation, it does not respond to any commands.

Answer 1

Failed to execute stat - seems to mean in this case that there is no such file or directory. And judging by the picture - nothing has moved, because there is nothing there. Therefore, launching from other directories does not work. I would delete everything and then from the very beginning:
Install composer globally:
curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer
Well, and then anywhere to check if it works: composer -V
