Liunx under Global installation Composer

I put it in the PATH of the system directory, so that it can be accessed globally.

Curl-ss Https://getcomposer.org/installer | PHPMV Composer.phar/usr/local/bin/composer

Note:if the appeal command fails because of permission execution, use thesudo try running mv againthat line of command.

Input command: Composer-vcomposer version 1.0-dev (FEEFD51565BB8EAD38E355B9E501685B5254D0D5)

The above words indicate that the installation was successful!
