Composer auto self-update

Question

It is frequently that every 30 days I will get this warning message:

Warning: This development build of composer is over 30 days old. It is recommended to update it by running "composer.phar self-update" to get the latest version. 

Then, I have to repeatedly do the update every 30 days. Is there anyway I can have the composer to auto update itself?

Thank you.

Answer 1

Composer doesn't have a feature to automatically run self-update to my knowledge. Also, running self-update by itself doesn't seem like the right way. Maybe you don't have permission? Then try using sudo, like: sudo composer self-update.

It is just a simple command, and you should only need to do it once about every 30 days. And keep Composer installed globally so you don't need to run it for each project.

Answer 2

For versions of composer which self-update is not yet available, just run the following commands:

1. php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');". This will download the composer-setup.php file into the current working directory;
2. php composer-setup.php. This will create the composer.phar file into the current working directory;
3. sudo mv composer.phar `which composer` . Replace the installed composer executable (in my case /usr/bin/composer) with the one from the previous step.

After you've done this steps the sudo composer self-update will become available.
