Unable to remove hirak/prestissimo

[amadhav1]

I am on a Macbook Pro Catalina
PHP: 8.0.2
Python: pip3 python 3.9
Vagrant 2.2.14
ansible 2.10.5
Coomposer 2.0.9

When I try composer --version or anything using Composer I get this

The "hirak/prestissimo" plugin was skipped because it requires a Plugin API version ("^1.0.0") that does not match your Composer installation ("2.0.0"). You may need to run composer update with the "--no-plugins" option.

Then I tried the instructions to remove it "composer global remove hirak/prestissimo", and I get this:

Changed current directory to /Users/xxx/.composer

Your requirements could not be resolved to an installable set of packages.

Problem 1
- consolidation/cgr is locked to version 2.0.4 and an update of this package was not requested.
- consolidation/cgr 2.0.4 requires php ^5.3.2 || ^7.0 -> your php version (8.0.2) does not satisfy that requirement.

Removal failed, reverting ./composer.json to its original content.
Removal failed, hirak/prestissimo is still present, it may be required by another package. See composer why hirak/prestissimo.

Any Idea how I can get rid of it so that I can use composer?

Any Idea how I can get rid of it so that I can use composer?

Your question is incorrect - you can use Composer, it's just a warning.

In your set up you have 2 issues (none of them is preventing you from using Composer):

• you have globally installed "hirak/prestissimo" which works with Composer 1 and you have Composer 2
• you have globally installed "consolidation/cgr" which requires php ^5.3.2 || ^7.0 and your php version (8.0.2) does not satisfy that requirement

So, when you are trying to remove "hirak/prestissimo" Composer fails to update dependencies because of the other issue.

You can either remove both problematic dependencies with
composer global remove hirak/prestissimo consolidation/cgr
or ignore the PHP version issue with
composer global remove hirak/prestissimo --ignore-platform-reqs
