can't install Prestissimo

[adeguntoro]

  Package hirak/prestissimo at version 0.3.8 has a PHP requirement
  incompatible with your PHP version, PHP extensions and Composer version

Right now i use Windows 7 Pro SP1, PHP 7.3.9 from XAMPP, and Composer 2.0.2. Is this normal ?

Same here, this is breaking our CI builds. We're running it in Ubuntu in docker containers.

Actually, if you're getting this error, you are probably running composer v2 now, which means it will download packaged in parallel by default, so that means you don't need this plugin anymore. see here: #230

Yep, Composer changed their latest tag to version 2. That's another reminder not to use latest in your builds.
So if you have this magic line in your docker:
COPY --from=composer /usr/bin/composer /usr/bin/composer
add :1 after composer like the following, to keep using version one, until you figure out the impact.
COPY --from=composer:1 /usr/bin/composer /usr/bin/composer
