Downgrade composer from 2.x to 1.x via brew

#composer #brew #downgrade

You just upgraded your brew packages and composer updated itself to version 2.x but you still need version 1.x? This is how you can downgrade (& upgrade again):

Show available versions of composer:

brew log composer

For me the latest 1.x version to date is: composer 1.10.15

Let's downgrade

composer self-update 1.10.15

To switch back to the 2.x version use

composer self-update --rollback

Let's downgrade
composer self-update --1

  --1                        Force an update to the stable channel, but only use 1.x versions
  --2                        Force an update to the stable channel, but only use 2.x versions
