New Composer version 2 is out and it is supposed to be way faster then version 1.So tried to update it using

composer global self-update --2

and

composer self-update --2

I however got into this error

Symfony\Component\Console\Exception\RuntimeException]
The "--2" option does not exist.

So did a global update of all packages installed:

composer global update
Changed current directory to /Users/jasper/.composer

Then I tried composer self-update --2 again, but did not help and stil had the same error. So did another try using verbose output

composer self-update --2 -vvv

Then I decided to do a general update of version 1 first

Use composer self-update --rollback to return to version 1.7.3

And then I got to version 2.0.5 funnily enough:

composer -V
Composer version 2.0.5 2020-11-06 20:57:15

So there was no need for the --2 after all. Perhaps cause version 2.x is stable now. Now let’s hope my Laravel installs play nice with Composer version 2 as I was told it would and be way faster!
