The process of updating composer

My local composer has not been updated since May 18. Now that you are using composer to indicate that 2.0 has been released, update it!

According to established thinking, composer supports command updates, that is, using the

Composer self-update

But it gave me a hint.

`SHA384 is not supported by your openssl extension, could not verify the phar file integrity`

Looking at the hint, it is because there is no way to verify the legitimacy of phar, so go to the official documents to find a way to deal with it.

Download the latest installation package:

Php-r "copy ('https://getcomposer.org/installer',' composer-setup.php');"

Check the hash value of the downloaded file:

Php-r "if (hash_file ('sha384',' composer-setup.php') = = '756890a4488ce9024fc62c56153228907f1545c228516cbf63f885e036d37e9a59d27d63f46af1d4d07ee0f76181c7d3') {echo' Installer verified';} else {echo 'Installer corrupt'; unlink (' composer-setup.php');} echo PHP_EOL;"

Confirm that the installation is successful:

Php composer-setup.php

Remove the link:

Php-r "unlink ('composer-setup.php');"

Move to the environment:
